Crash in commandhelper.js

[cwit-vcas]

Description

The extension often crashes resulting in a complete gnome crash
I have noticed this happens when using matplotlib or virtualbox.

Steps to Reproduce

Just use virtual box with a windows guest, will crash after a short while.

Screenshots

I have this stack trace.

Hi,

I'm having a very similar problem since today, but my logs differs slightly. Maybe it can help tackle the problem :

Trop de fichiers ouverts = Too many open files

Encountering same problem as original poster. Same stack trace.

I issued a new release fixing this crash. Sadly as mentioned in the previous release GLib freezes the UI while spawning a command. The only way I found to use posix_spawn apparently introduces crashes. I will find another solution. Thank you for submitting your report.

@cwit-vcas @lhall-amphibee @beerendlauwers
I issued a new release trying to resolve this issue but this time the new subprocess procedure is an experimental feature that needs manual activation. I tested it extensively and didn't have any crash or bug, can you please try as soon as the new release come out to enable the flag and check if you encounter any crash? Thank you.

I am still getting crashes with "Too many open files errors"

I get logs like this in journalctl for a long time and then eventually something crash.
I do have the "PosixSpawn" flag enabled, but also saw the same behavior before it was enabled.

I'm actually working on an issue that might be related to this one.

[icyrockcom]

Just to chime in here, I still see the issue with version 34 (EGOv51). I'm on NixOS if that matters.

Sampling the lsof output for gnome-shell pid shows that it creates a FIFO pipe every second, eventually breaching the 1024 limit. Disabling the extension immediately drops the file count and it stays constant afterwards. Enabling the extension immediately shows the increasing trend.

Also, not sure if I'm doing something wrong, but the PosixSpawn Subprocess is reset to disabled any time I disable / enable Astra Monitor extension itself.

Let me know if there's something I can do to help with troubleshooting.
