Anything else we should know?

to rule out any issues with my OS, i performed a reinstallation on July 22, 2022. I streamed on July 23, 2022 and OBS crashed at the above time frame

On July 24, 2022 I streamed again with gdb and OB crashed again

You exited before getting the full output from gdb. Please try again and continue at the prompts for more output instead of exiting. bt is good enough there is no need for bt full.

You have some audio related third party plugins, can you remove them and see if this solves the issue?

[oparada1988]

Interesting,

I dont have any audio plugins, I have websocket(https://github.com/obsproject/obs-websocket) and the below plugins:

Do you think it could be related to pipewire? Installed it using this guide: https://github.com/mikeroyal/PipeWire-Guide

Ill go ahead and uninstall pipewire and try again

[kkartaltepe]

if phandasm_waveform_source is not reading or writing audio data into obs then that's probably fine. If you have time to test with/without pipewire that would be helpful as well.

Just an update, I was able to do a test stream for 2 hours without crash after removing pipewire.

Will proceed to retest in a real world situation. will report back

I was not able to replicate a crash on the current master version with pipewire 0.3.55 after recording for 2h15m with one stereo device.

Looking at the log it seems you are using a version of pipewire that isnt distributed with ubuntu 22.04 which may cause issues with trying to use our PPA.

Hello, I just completed a stream of 2:30 with no crash. It appears the above PPA of pipewire is the cause of the issue. Going forward I will try to install the master branch of pipewire.

Thanks for your help, this ticket can be closed!
