vscode-elixir-ls Memory and High CPU Usage

I was working on the Tesla package and went to sleep. When I resumed work, I noticed that my computer was almost unresponsive. The extension had consumed all available RAM and spiked the CPU.

This is not the first time it has happened; just that this time, I didn't close it or click on the extension's notification complaining about compilation errors or something else.

Environment

Elixir & Erlang versions: Elixir 1.16.2, Erlang/OTP 26
VSCode ElixirLS version: v0.20.0
Operating System Version: macOS 14.2.1

Troubleshooting

[x] Restart your editor (which will restart ElixirLS) sometimes, fixes issues
[x] Stop your editor, remove the entire .elixir_ls directory, then restart your editor

I have the same problem, make it almost unusable.

May 03 '24 06:05 fnicastri

Any way to reproduce this?

May 03 '24 06:05 lukaszsamson

it's up high cpu and memory when I saved

May 04 '24 04:05 vuluu2k

I get this behavior even with a clean phoenix project

May 04 '24 13:05 fnicastri

same high CPU and memory problem for me, still not sure what triggers it, I got it with a simple project.

Is there a way to log some memory/threads dump of the beam.smp when killing it?

Similar environment:

Elixir & Erlang versions: Elixir 1.16.2, Erlang/OTP 26
VSCode ElixirLS version: v0.21.0
Operating System Version: macOS 14.4.1 (M1)

May 05 '24 13:05 asantare

I've found a way to reproduce it:

I have a project with a simple module with few functions but without use directive
open the project in vscode
open the simple module
write use GenServer (slowly)
boom, the beam.smp goes high cpu and memory usage

here the log from the pluging output window:

May 06 '24 05:05 asantare

hi @lukaszsamson, there is an issue on elixir-ls, somehow related, and a comment about the macro expansion.

How come the beam get stuck in high cpu usage (in loop?) when trying to expand a non existing macro? (from the log in previous comment it seems it tries to expand 'GenSe') Can it be tracked/reproduced on beam side?

May 06 '24 06:05 asantare

@asantare thanks, I can confirm there is an infinite loop issue with incomplete code

defmodule Some do
  use
  @spec my(number()) :: number()
  def my(abc) do
    abc + 1
  end
end

May 06 '24 08:05 lukaszsamson

@yordis @fnicastri @vuluu2k are your scenarios similar to what @asantare found?

May 06 '24 08:05 lukaszsamson

@lukaszsamson

nope, I'm sorry but I misread the topic. Probably my case is unrelated to the extension.

In my case whenever I start a Phoenix/Ecto process in the debugger the process start to eat all the memory. But I have no idea if the two cases can have something in common.

This was now, latest stable versions of everything.

May 06 '24 13:05 fnicastri

@fnicastri That's most likely unrelated. For reference https://github.com/elixir-lsp/elixir-ls/issues/1017

May 06 '24 13:05 lukaszsamson

@lukaszsamson

yep, it was me ;)

I thought I answered you but then I got overwhelmed by work...

May 06 '24 13:05 fnicastri

It could definitely be a macros problem, that, it fails to compile and then it never gets to work later.

I have run into compilation issues that keeps showing notifications messages even thou it is fixed

May 06 '24 20:05 yordis

@asantare issue fixed in https://github.com/elixir-lsp/elixir_sense/commit/8ec03beb7bbaa0d53dd33cb68ad98ad945cf9cf5

May 07 '24 05:05 lukaszsamson

@yordis can you try attaching observer to language server? To do so

Create a local setup script in $XDG_CONFIG_HOME/elixir_ls/setup.sh or $HOME/.config/elixir_ls/setup.sh (whatever is defined on your system)
Enable distribution in your local setup script e.g. export ELS_ELIXIR_OPTS="--sname language_server"
Restart language server
Run iex in terminal iex --sname foo and :observer.start() You should be able to switch node to language server and inspect what is using up the resources

May 07 '24 06:05 lukaszsamson

@lukaszsamson I am trying to remember to follow up on this, but it will require to wait at least until next week. Sorry!

May 07 '24 06:05 yordis

+1, massive resource usage seemingly after the last update

May 07 '24 16:05 njwest

+1 on this as well. Killing my CPU's performance.

May 07 '24 16:05 wsbinette

Same here. As soon as I type use GenServer the computer become unresponsive. Same problem after typing use Application. After I kill VSCode, it takes several minutes for computer to recover. Then, after restarting VSCode, it is usable again; until I need to use another behaviour...

Edit: Temporary solved the issue by downgrading the extension to version 0.20.0

May 07 '24 20:05 mihaiphilip

v0.21.1 with fix for use problem has been released.

May 08 '24 06:05 lukaszsamson

Thanks a lot! :green_heart:

I don't think use is the only problem though. I had it eat my entire memory again apparently on the new version and I was "only" working on seeds.exs so no use in use. It also seems to die so fast that I can't attach observer, or at least when I notice it the computer is already sluggish and then I have seconds to close vscode before all memory blows up :sweat_smile:

May 08 '24 12:05 PragTob

I agree with @PragTob. It seems to get caught up on def function(), do: one line syntax as well. It kills the syntax highlighting and then my CPU goes crazy. This may be worth it's own issue report, but I'll just put this here for now.

@wsbinette do you have a more complete repro? I tried def function(), do: and couldn't hit it.

@HarshBalyan please use steps from https://github.com/elixir-lsp/vscode-elixir-ls/issues/417#issuecomment-2097509466 to diagnose.

May 09 '24 15:05 lukaszsamson

I'm seeing the same on v0.21.1, albeit much "slower" in memory usage growth compared to previous version.

A first check seems that what is increasing is ETS usage (most of the memory according to observer is there), will try to keep an eye on which table is increasing.

May 09 '24 16:05 xadhoom

@wsbinette do you have a more complete repro? I tried def function(), do: and couldn't hit it.

I'll see if I can get a consistent repro for it 👍🏼 Might take a minute tho, sorry!

May 09 '24 18:05 wsbinette

A first check seems that what is increasing is ETS usage (most of the memory according to observer is there), will try to keep an eye on which table is increasing.

Follow up: ETS is indeed doing "something".

On the very same project, at startup I've 35 ETS tables with 542MB memory usage (by ETS itself). After sometime of working, I have 45 ETS tables, using ~1.2GB of memory. Some screenshots for reference (taken an startup and after a while). This happened in less than our hour.

erlang-ls-observer-ets-startup erlang-ls-observer-ets-2 erlang-ls-observer-ets-3

There're some duplicated tables, with same number of objects and usage, but maybe is by design. I'll keep an eye on the observer, today had a crash due to after a day of work (and no observer open :( ), so It may need time to happen again.

May 13 '24 16:05 xadhoom

Thanks @xadhoom Those duplicated tables are from the new incremental dialyzer. My hypothesis is that when it crashes it recreates the tables. I’ll work on a fix and until then I suggest switching back to the old dialyzer

May 13 '24 17:05 lukaszsamson

After one hour of light editing a project. just editing/removing Logger calls

Screenshot 2024-05-14 at 9 31 44 AM

May 14 '24 07:05 fnicastri

@fnicastri you can fire up the observer as explained here to check where this memory is used. Or disable the incremental dialyzer in vscode preferences.
