webrtc A simple reader and write for MPEG-2 transport stream

This is a tracking issue for making a simple MPEG transport stream (.ts) format for HEVC and AVC examples. I need it to make write and read from disk example for HEVC (I'm currently working on fixing the RTP de-packetizer).

Turns out I was chasing a ghost. The reason destroy wasn't called by sv2-tp was not because of a missing context param, but because of an unrelated regression.

So the memory leak @plebhash is seeing is probably due to not calling destroy.

re: https://github.com/bitcoin/bitcoin/issues/33899#issuecomment-3570523079

it looks like you found a real bug. Because BlockTemplate::createNewBlock doesn't have a context param, it looks like its destroy method is not invoked until sv2-tp disconnects.

I can imagine there's a bug causing the block template not to be freed until the disconnect happens, but I don't think createNewBlock method having a context parameter would affect this. Having a context parameter just allows the method to run on an asynchronous thread without blocking the event loop, instead of running on the event loop thread. But which thread the block was created on should not affect how it's destroyed

re: https://github.com/bitcoin/bitcoin/issues/33899#issuecomment-3570541428

but do we have to explicitly call destroy or is it sufficient to drop the reference from memory on the client side?

from my understanding of capnp, I believe it should be sufficient to drop it from memory, but on the other hand there must be a reason for destroy to exist?

Your understanding is right, I think, but there are a lot of details here and I can imagine there being some bug where just dropping the reference on the client side does not delete the server side object right away. The reason for having an explicit destroy method is to give clients a way to destroy the server side-object and actually wait for it to be destroyed. If clients just drop their references to server side objects, the server side objects will get destroyed, but it will happen asynchronously.

Nov 24 '25 14:11 ryanofsky

I ran two sessions with https://github.com/bitcoin/bitcoin/pull/33936 at a3a6861e131120eabf6e2f7ecd15e5ea805c66b2, where the client was our Sv2 Rust code

both of them had at least one chain tip update, which should trigger templates being flushed from memory (so I'd expect to see a sharp decline in RAM consumption)

in the first one, we're not calling destroy:

in the second one, we're calling destroy after chain tip updates:

I guess this indicates that @Sjors approach on https://github.com/bitcoin/bitcoin/pull/33936 isn't fully fixing the issue yet, which I guess is already known due to this comment https://github.com/bitcoin/bitcoin/pull/33936#issuecomment-3570998560

do we have to explicitly call destroy or is it sufficient to drop the reference from memory on the client side?

Following up on this, it's good practice to call destroy methods on objects which have them, to guarantee the objects are destroyed right away instead of asynchronously. This is most important if objects have nontrivial destructors, or if it matters what order objects get destroyed.

Block templates using a lot of memory in a memory-constrained environment could be another reason to call destroy explicitly. But if adding destroy calls to the client fixes a memory leak, this does sound like a bug, because memory should be freed soon after references are dropped even without explicit destroy calls.

re: https://github.com/bitcoin/bitcoin/issues/33899#issuecomment-3570523079

its destroy method is not invoked until sv2-tp disconnects

The reason destroy wasn't called by sv2-tp was not because of a missing context param, but because of an unrelated regression.

I was looking into this to remind myself what current behavior is. It actually changed sort of recently, but before the 30.0 release in https://github.com/bitcoin-core/libmultiprocess/commit/949573da84112388f68d1893f55aae0ca7f12d0c from https://github.com/bitcoin-core/libmultiprocess/pull/160. The commit mention there mentions "this change causes the ProxyServer::m_impl object to be freed shortly after the client is freed, instead of being delayed until the connection is closed."

Before that change, libmultiprocess would only delete server objects if the client explicitly called a destroy method, or when the connection was cleaned up. But currently it should delete them immediately even if a destroy method is never called. The previous behavior didn't matter very much for libmultiprocoess c++ clients call which destroy() internally in their own destructors, but could matter for rust and python clients which don't do that.

here are some insights from the experiments I’ve been running over the past few days.

When I first reported this issue (https://github.com/stratum-mining/sv2-apps/pull/59#issuecomment-3568252007), my server was also running a few utility tools that I typically use during long test sessions.

To eliminate the “maybe it’s something else eating the memory” hypothesis, I started a fresh session with only the following running:

sv2-apps
Bitcoin Core v30 (mainnet)
The essential system processes (no extra utilities, no accessories)

Server specs (VPS):

2 vCPUs
2 GB RAM

Ubuntu 24.04 LTS

Distributor ID: Ubuntu
Description:    Ubuntu 24.04 LTS
Release:        24.04
Codename:       noble

Baseline Start

At startup, with the full SV2 stack running (two apps using IPC), the total memory usage hovered between 800 MB and 1 GB, with some expected minor spikes.

After letting it run overnight, the total VPS RAM usage sat around 1.5 GB.

During that same period:

Bitcoin Core increased by roughly 160 MB
But the rest of the increase could not be explained by Bitcoin Core alone
This made me suspect the sv2-apps were also growing over time
A few hours later, @plebhash confirmed with psrecord that the apps were indeed growing as well

Next 8 Hours

Over the next 8 hours, total RAM usage climbed from 1.5 GB → 1.6 GB.

Since I had a bit of headroom left, I decided to stress things slightly.

Adding More Load

Alongside the already-running apps, I launched three more pool instances (also using IPC).

Within ~3 hours:

Bitcoin Core’s RAM usage increased (expected because of more IPC traffic, I think)
Total RAM climbed to 1.75 GB

I then shut down the extra pool instances.

However:

Bitcoin Core did not release the memory
Even by the next morning, RAM usage was still between 1.69–1.75 GB
So it seems Bitcoin Core doesn’t reduce its memory footprint after clients disconnect

The screenshot is half an hour after I closed the extra pool instances.

Final Incident (Today)

Since the VPS was close to running out of RAM again, I repeated the test: I spun up one more pool instance using IPC. RAM usage jumped to ~1.82 GB.

I closed the pool instance and waited to see if memory would drop. It didn’t.

A few hours later, the OS killed Bitcoin Core:

Tue Nov 25 14:51:01 2025] Out of memory: Killed process 2763434 (bitcoin-node) total-vm:13471820kB, anon-rss:1302224kB, file-rss:2916kB, shmem-rss:0kB, UID:0 pgtables:19496kB oom_score_adj:0

So at the moment, Bitcoin Core ends up consuming about 1 .3GB of RAM and never seems to shrink back down.

Why I’m Reporting This

I’m sharing these observations because they might help narrow down the behavior we’re seeing, both in Bitcoin Core and the SV2 apps.

I’m also willing to run another clean testing session. If you have recommendations for specific instrumentation or profiling tools to run, I can set them up. Right now, I avoided using things like psrecord during the run so I could rule out secondary tools affecting the memory footprint.

@lucasbalieiro does Bitcoin Core behave better if you compile the 30.x branch from source? That's the equivalent of how v30.1 will behave when it comes out.

@lucasbalieiro does Bitcoin Core behave better if you compile the 30.x branch from source? That's the equivalent of how v30.1 will behave when it comes out.

Built Bitcoin Core at commit a14e7b9dee9145920f93eab0254ce92942bd1e5e:

root@srv-f20833:~/Projects/bitcoin/build/bin# git log
commit a14e7b9dee9145920f93eab0254ce92942bd1e5e (HEAD -> 30.x, origin/30.x)
Merge: d0f6d9953a ae63cc4bf2
Author: merge-script <[email protected]>
Date:   Thu

Ran the same stress test again (spawning multiple IPC-heavy apps).

Observed differences:

Core feels noticeably more tolerant. Baseline RAM usage is ~100 MB lower. I could spin up more apps simultaneously without Core hitting big spikes, looks like it’s using less memory per connected app.
However, after disconnecting the extra pool I used for stress testing, the RAM doesn’t drop back down to the original baseline (the level seen when only the SV2 apps + Core were running). It stays elevated, as if it’s still serving several pool apps.

Even when disconnecting all the apps. It does not return to its ~700MB of consumption

Nov 25 '25 21:11 lucasbalieiro

Thanks the the updates! If I'm understanding correctly, it seems like memory usage increasing 160MB overnight and 100MB over next 8 hours, and this would be pretty consistent with block templates not being freed. I think there are two key unknowns here:

We don't know whether the client is holding onto the block template references. If it is, then the memory usage going up would be expected and this is client bug, otherwise it is a server bug.
We don't know if server is failing to release block templates when the client disconnects. The fact that RSS number does not decrease when the client disconnects suggests that server is failing to release memory, but it's not a reliable indicator, because it only show much memory has been allocated by the OS to the process, but not how much memory is actually in use by the process. When the C library frees memory, it's normal for it to hold onto the pages that were in use and not return them to the OS. It's possible to see how much memory is actually in use using a tool like heaptrack

Probably a good next step would be to add log statements to BlockTemplateImpl constructor and destructor and write a python test program creating a template, and seeing if the destructor is actually called on sudden disconnect, or when calling the destroy method, or when just deleting the reference with del template; await asyncio.sleep(0). This could indicate if there's an obvious problem with the IPC server. It does seem like there is a real leak here, but it's not clear if it this is caused by a bug on the client side or server side.

Nov 26 '25 01:11 ryanofsky

The node log messages should contain a destroy entry every time the client releases a template. It's probably also a good idea to have the client emit a log message when it discards a template. If the client waits until disconnect you'll see a flood of destroy methods at that point.

If the latter isn't happening, that could suggest a bug where Bitcoin Core doesn't release the memory after the client disconnects. As suggested by @ryanofsky adding logging to BlockTemplateImpl and ~BlockTemplateImpl should reveal this.

Nov 26 '25 09:11 Sjors

we merged https://github.com/stratum-mining/sv2-apps/pull/59 so deploying SRI Pool and/or JDC for testing can be done from main branch

The node log messages should contain a destroy entry every time the client releases a template. It's probably also a good idea to have the client emit a log message when it discards a template.

I just did some tests with:

Bitcoin Core v30 binary downloaded from official website
mainnet (for frequent template updates)
SRI Pool from commit https://github.com/stratum-mining/sv2-apps/commit/ecf5f258766ac9e08bd8aaaa53b45b1c1bf961d8 (and also RUST_LOG=debug for extra verbosity)

on Pool logs, after block 0000000000000000000077e34472247575f4858357541269d56a8df5b429862b, we destroyed 84 stale templates:

Following up on https://github.com/bitcoin/bitcoin/issues/33940#issuecomment-3578402033, I added log statements to the BlockTemplateImpl constructor and destructor and wrote a python test creating a block template object and calling the destroy method or not (DESTROY variable), and deleting the python template variable or not (DEL variable). As soon as either of these things were done, I could see the ~BlockTemplateImpl destructor being called. I could also see the destructor being called just disconnecting regardless of whether these things were done. I tested with current bitcoin master and with the v30.0 tag and saw the same behavior in both.

This test would seem to indicate that the leak is happening on the rust client side, and that when the bug happens, the client is probably not dropping references to all old templates or calling destroy on them, since doing either of these things should be sufficient to free memory on the server. It is possible there is a more subtle bug on the server side, and not a problem on the client, but so far I haven't seen behavior that looks like a problem. The test program looks like:

re: https://github.com/bitcoin/bitcoin/issues/33940#issuecomment-3582775203

after block 0000000000000000000077e34472247575f4858357541269d56a8df5b429862b, we destroyed 84 stale templates: [...] all of this come from the execution of TemplateData::destroy_ipc_client, where we allocate one dedicated server thread, and then destroy each template sequentially

@plebhash, I'm trying to figure out what these logs mean. One thing I'm not sure about is why exactly the rust client is keeping 84 block template references. Is this because of lack of interruptWait method and inability to delete templates before waitNext() returns? Or are the references being kept because the blocks might need to be submitted? Or maybe some other reason?

I guess from looking at the rust code, it is currently designed to hold onto all templates and then free them when the tip changes. If so, this seems reasonable and should hopefully not use too much memory since the blocks should contain many of the same transactions. I guess the logs also indicate that rust code is able to trigger blocktemplate deletions on the server side, so this also seems good. If I'm understanding correctly, your logs here seem to show the rust client behaving well and deleting the templates it doesn't need.

One thing I'm not sure about is why exactly the rust client is keeping 84 block template references.

We are conservatively keeping all templates in memory up until a chain tip update, because we could potentially receive a solution to any of them.

This might change with https://github.com/bitcoin/bitcoin/issues/33899, but the limit will remain something to be configured on Bitcoin Core, and whenever waitNext returns Overloaded error, we discard the oldest template.

Is this because of lack of interruptWait method and inability to delete templates before waitNext() returns?

no, so far I haven't noticed any meaningful limitations around deleting templates being imposed by the lack of interruptWait

I guess from looking at the rust code, it is currently designed to hold onto all templates and then free them when the tip changes.

correct.

If so, this seems reasonable and should hopefully not use too much memory since the blocks should contain many of the same transactions.

we don't keep transaction data on the client side... whenever it's needed, we fetch it via getBlock ad-hoc.

If I'm understanding correctly, your logs here seem to show the rust client behaving well and deleting the templates it doesn't need.

yes, that's also my understanding... the puzzling thing is that we're still having the memory leaks... so we're either missing some detail on this analysis, or the cause is related to something other than templates

I think at this point we've ruled out the obvious possible causes of leaks, and need to start debugging the issue more directly.

It would help to have some steps to reproduce. If someone can let me know what code to check out and build, and what commands to run that will show the increasing memory usage over time, that would be great. As long as we can observe it happening we should be able to figure out the cause.

launch Bitcoin Core on mainnet (for high mempool activity)
git clone https://github.com/stratum-mining/sv2-apps -b v0.1.0
edit sv2-apps/pool-apps/pool/config-examples/mainnet/pool-config-bitcoin-core-ipc-example.toml to make sure unix_socket_path is set correctly
cd sv2-apps/pool-apps/pool; cargo run -- -c config-examples/mainnet/pool-config-bitcoin-core-ipc-example.toml

at this point, you can start monitoring RAM

I used psrecord: psrecord $(pgrep bitcoin-node | head -1) --plot plot.png

but it also consumes a lot of RAM itself (so the OS might kill it if your system doesn't have enough and you run it for too long), so maybe there's more sophisticated ways to do this kind of instrumentation

re: https://github.com/bitcoin/bitcoin/issues/33940#issuecomment-3611006053

git clone https://github.com/stratum-mining/sv2-apps -b v0.1.0

Thanks for the instructions. I've been experimenting with the v0.1.0 pool_sv2 app on regtest with a python script to generate transactions & connect blocks quickly to make a memory leak happen without needing to wait a long time.

So far, behavior has been mostly as expected, where generating lots of transactions without connecting new blocks causes block templates to accumulate and memory usage to go up, but when a new block is connected, the templates get released by the mining client.

One thing I saw that was surprising was that if the python client connected blocks too quickly, the mining client seemed to fall behind and only release templates after a delay. Like the mining client would be calling destroy method on the template from block height 5000 when block height 5015 was being connected. But pausing the python script would cause the mining client to catch up.

I guess I need to try letting the code run a longer time to see if memory usage will accumulate. But I think a slow & gradual leak could be pretty difficult to debug and fix. So if there's anything that can be done to trigger a leak quickly, it will make this debugging this issue a lot easier.

if the python client connected blocks too quickly, the mining client seemed to fall behind and only release templates after a delay

There's a hardcoded 10(?) second grace period where the Template Provider (both implementations) hold on to templates after a new tip is connected. It's there for two reasons:

Trying to relay the block anyway (requires further node changes, since we currently honour the first-seen rule even when that means "our" block loses)
Giving pools a chance to verify the template (via JDS) and award shares (especially in schemes that reward both hash power and total fees)
