FrankenPHP crashes with zend_mm_heap corrupted while running some wordpress sites

Open walmartshopper opened this issue 6 months ago ‱ 25 comments

What happened?

While testing out a migration from nginx/php-fpm to FrankenPHP, the server crashes with "zend_mm_heap corrupted" after around 8 hours of uptime. This is using the debian package of FrankenPHP 1.8.0.

The server is hosting 6 fairly basic wordpress sites and a few static sites.

Can you also share the plugins that you are using or a small reproduction repo of how the wordpress site looks like?

To figure out if this is related to #1530, it would also help if there's some kind of monitoring on memory (if it increases over time).

AlliBalliBaba avatar Jul 09 '25 22:07 AlliBalliBaba

It would be fairly time consuming to set up a reproduction repo with all six sites, so below is the list of plugins for each site. I also searched the code for calls to opcache_invalidate(). Wordpress has its own wp_opcache_invalidate which calls opcache_invalidate() behind the scenes. It looks like when updates are installed, it calls opcache_invalidate() on all the wordpress files which appears to be several hundred. Also the plugin W3 Total Cache uses opcache_invalidate(), but I think only when I manually clear the cache. In W3 Total Cache I have enabled APCu page caching and object caching, but I don't know if that has anything to do with it. My suspicion is that the core wordpress updates calling opcache_invalidate() on hundreds of files at a time might be the culprit.

Not sure if it helps, but I will also say I have a second server running the exact same environment (t4g.medium instance running Debian bookworm arm64 and using FrankenPHP 1.8.0 .deb install). This server is running my own custom code with no wordpress or any other framework, and it has not crashed. The code on this server does not make any calls to opcache_invalidate(). The server that is crashing is low traffic and probably averages less than 1 request per second combined across all the hosted sites.

I am currently doing memory monitoring and will compare memory usage after frankenphp startup vs after a few hours and report back.

walmartshopper avatar Jul 10 '25 01:07 walmartshopper

I was able to crash FrankenPHP fairly quickly just by going to the wordpress admin dashboard updates page and clicking "Reinstall version 6.8.1" a few times. FrankenPHP crashed during the 4th or 5th reinstall.

walmartshopper avatar Jul 10 '25 01:07 walmartshopper

Hmm yeah I imagine 'Reinstall version' does some kind of opcache flushing, I'll try to setup an actual wordpress installation and see if I can reproduce it.

@withinboredom I remember you mentioning using FrankenPHP with wordpress at some point, have you ever encountered something similar?

AlliBalliBaba avatar Jul 11 '25 20:07 AlliBalliBaba

If this is a thread safety issue, as a workaround, maybe could we override opcache_invalidate() to add some locking mechanism?

dunglas avatar Jul 12 '25 06:07 dunglas

have you ever encountered something similar?

No because I use docker images + composer for upgrades/installs/etc.

withinboredom avatar Jul 12 '25 11:07 withinboredom

@dunglas this is not just a thread safety issue, it can also be an issue with FPM (see here).

So far it's just a guess, but this could be similar to #1530. The issue there was that accumulation of memory from opcache_invalidate would eventually force an opcache_reset. But under concurrency PHP can't always schedule that flush safely. Could also be something else though.

AlliBalliBaba avatar Jul 12 '25 14:07 AlliBalliBaba

I guess it might be possible though to force all threads into a 'suspended' state on opcache_reset, similar to how we do it on worker restarts.

AlliBalliBaba avatar Jul 12 '25 20:07 AlliBalliBaba

Came here as I tested running moodle using frankenphp and also faced zend_mm_heap corrupted. Using frankenphp v1.9.0 binary release on M3/M4 Mac. Can reliably reproduce by trying to run the moodle setup - script below can be used to do so repeatedly.

#!/bin/bash
echo zend.exception_ignore_args=true > php.ini
echo max_input_vars=6000 >> php.ini

docker run --rm -d --name moodlepg -ePOSTGRES_USER=moodle -ePOSTGRES_PASSWORD=moodle -p5432:5432 postgres:17.4

test -d moodle || git clone --depth=1 https://github.com/moodle/moodle.git

echo "Next, visit http://localhost and try setting up moodle using Postgres /w user/pass = moodle"
# Moodle setup crashes after confirming successful "server checks" page
# Sometimes, it will segfault without printing the `zend_mm_heap corrupted` message.
echo "When done: docker stop moodlepg"

cd moodle && env PHP_INI_SCAN_DIR=.. frankenphp php-server

After installation error has been triggerd once, it seems the error can be re-triggered by reloading http://localhost/public/admin/index.php?cache=0&agreelicense=1&confirmrelease=1&lang=en

Adding opcache.enable=false to php.ini completely solves/circumvents the issue. Hope this helps to track the issue down - although not related to wordpress.

schnoddelbotz avatar Jul 29 '25 11:07 schnoddelbotz

@schnoddelbotz yeah this is definitely connected to opcache_reset(), removing all references in the moodle code makes this not crash.

PHP actually exposes a function to hook into a reset, namely zend_accel_schedule_restart_hook. Might be possible to make a reset fully safe by forcing all threads into a restart when the hook is called.

I have the same issue with apps in Sylius, Drupal and others (using docker images)

Renrhaf avatar Nov 24 '25 08:11 Renrhaf

I have the same issue on nextcloud when I update lot of apps.

I can reproduce it this way: There's a "bundle installation" button that can install 4/5 applications and then I got these messages :

2025-11-25T12:41:01.420428769+01:00 zend_mm_heap corrupted
2025-11-25T12:41:05.648781639+01:00 {"level":"info","ts":1764070865.648729,"msg":"maxprocs: Leaving GOMAXPROCS=16: CPU quota undefined"}
2025-11-25T12:41:05.648864867+01:00 {"level":"info","ts":1764070865.6488445,"msg":"GOMEMLIMIT is updated","package":"github.com/KimMachineGun/automemlimit/memlimit","GOMEMLIMIT":29412830822,"previous":9223372036854775807}

then caddy/frankenphp restart (but the bundle installation failed). And that only happen on kubernetes, not on docker only stack

If I install these apps manually (one after another) then it's not crashing.

Using frankenphp 1.10 and php 8.4.15

GreyXor avatar Nov 25 '25 11:11 GreyXor

Thanks for the reproducers, this is definitely a race condition with calling opcache_reset repeatedly and concurrently and might need a fix in php-src. I tried some stuff on our end, but was not successful to make it fully safe as of yet.

AlliBalliBaba avatar Nov 25 '25 23:11 AlliBalliBaba

We are getting them, but for our Laravel services, not very often though, and it happens on a wide variety of url.path's, so don't think its something to do with specific application code.

firecow avatar Dec 03 '25 06:12 firecow

@firecow this is almost always an issue with something in C corrupting memory due to doing something non-thread-safe (or something else, but that's the most common one). In the issue prior, this was due to calling opcache_reset(). It can also be due to an extension, a bug in php, or somewhere else. Do you have any way to reproduce it reliably?

withinboredom avatar Dec 03 '25 06:12 withinboredom

For the opcache_reset() problem, couldn't we replace the original function by a new one wrapping it around a global lock that pauses all incoming requests? This should prevent the issue IIUC the issue.

dunglas avatar Dec 03 '25 16:12 dunglas

@dunglas it would have to halt all PHP processing in-general. There's no locks around opcache reads (there are on writes though), so the proper fix is to add rw-locks to php-src (which got a strange amount of resistance) or work around it by draining workers, stopping them, resetting opcache, and then restarting them.

withinboredom avatar Dec 03 '25 16:12 withinboredom

Maybe could we wait for all current PHP requests to finish, flush the cache, then unblock buffered requests.

This is not really optimal, but at least it will prevent the crash.

dunglas avatar Dec 03 '25 16:12 dunglas

And hang the server until it's done đŸ€Ș

I also had a quick look and wordpress seems to make use of several MT-unsafe functions like strtok, setlocale, getenv/putenv and others. opcache_reset seems to only be called on an explicit clear cache button press.

https://github.com/php/php-src/pull/14803 here's an open pull request somewhat related to it, but funny enough it seems like the slowing down part of the fix/workaround is not acceptable in php-src.

We already overwrite putenv and getenv to make them safe. Are strtok and setlocale really unsafe? From quickly testing they seem fine under high concurrency.

Maybe could we wait for all current PHP requests to finish, flush the cache, then unblock buffered requests.

I tried something similar, the issue was that an opcache_reset can also be triggered for other reasons, like memory filling up due to many calls to opcache_invalidate(). But it might be a good intermediary solution.

And hang the server until it's done đŸ€Ș

IMO hanging the server shouldn't be an issue as you should not call opcache_reset() on a super-busy production server anyways.

Yes, they are MT-unsafe in libc under linux and macos (not under windows). Chances are rather low to crash as they're extremely quick, but it can happen.

I have an open PR in php to make setlocale thread safe and maintainers seem to consider it a bug fix, so we might not have to do anything about it with 8.2 still in the support window.

Yeah, but in that optimal scenario it wouldn't crash either way. Of course it's better to hang a bit than crash & restart, though, especially for api or non browser activity that won't automatically reconnect.

Sorry, if this is totally stupid, but is there a way to "segment" the opcache for workers?

If an opcache_reset is triggered the workers are notified there's a new SHM address, they finish their current request, if any, and all subsequent requests use the "new" opcache. The remaining problem I see in this scenario (sorry again if this is unqualified nonsense) is cache stampede, but this would currently be a problem for any cold server too, right?

In the bigger projects I was running opcache never needed a lot of memory, so even with a lot of workers I can't see almost double the requirement (at worst with a lot of hot workers) being a problem.

Not without a change how opcache and its shared memory are implemented in php-src.

Just to add my experience from the zend_mm_heap corrupted message today... I know nothing about Zend internals, but Claude.ai seems to know everything and it diagnosed that my issue was that I was using PHP built in Redis (which is well known to not be thread safe) while using frankenphp worker mode. I let claude recommend, and it suggested to use Predis PHP Library instead, (milliseconds slower as not "built in" but perfectly acceptable) and this RESOLVED all my zend_mm_heap corrupted issues and I have not had a single issue since.

Claude.ai doesn't "know" anything.

It is? Sounds like hallucination to me, especially considering that I've been using FrankenPHP and redis in production for half a year. The extension lists thread safety as supported, too.

I let claude recommend, and it suggested to use Predis PHP Library instead, (milliseconds slower as not "built in" but perfectly acceptable) and this RESOLVED all my zend_mm_heap corrupted issues and I have not had a single issue since.

I have no reasonable explanation for that.

Like I said, I was just sharing my "experience" today, and "I know nothing"

I believe what claude is finding is this reference, the same as the google search AI shows above search results: https://github.com/phpredis/phpredis/issues/2029

PhpRedis does support running under ZTS mode, but not sharing a single Redis object between multiple concurrently running threads.

But then who knows...

I have no reasonable explanation for that.

Nor do I, but as soon as symfony sessions (in this new project) were moved to Predis, and all interactions with redis refactored to be through predis, I have not had a single zend_mm_heap corrupted message in the logs... no idea.

The other things it proposed doing instead of Predis was to set a env var USE_ZEND_ALLOC=0 for whatever reasons, but I ignored that and went for Predis.

I've been using FrankenPHP and redis in production for half a year.

So have I, the whole mySites.guru service runs bleeding edge versions upgraded within an hour of PHP and frankenphp releases as dunglas knows, accross multiple servers and services. That project uses Predis and dockerized images for frankenphp. Never had a single zend_mm_heap corrupted in production ever.

ok @henderkes of course you were right, back to zend_mm_heap with worker mode ... no idea why it settled down for a while after the Predis refactor, but it never solved it like I thought... oh well. Switching off worker mode again until someone with skills can find a cure for numpties like me.
