Bug Report Crashing while OBS is left running without capturing

#1
Hello I am using Linux Kubuntu 16.04 LTS and my system will crash after some time with OBS running but not in capture mode.

I have done this a few time and each time after a few minutes my entire system crashes and reboot automatically, and I can't figure out why?

I am using the official ubuntu ppa to install obs and have upload the following log files:

uname -a
Linux karma 4.15.0-24-generic #26~16.04.1-Ubuntu SMP Fri Jun 15 14:35:08 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I also have a dual monitor setup, when the crash happen I have firefox quantum "61.0 (64-bit)" running and I am watching youtube as a way to put some load on the system.

This seems to manifest after I switch to use the NVidia recommended driver, even after I switch back to Nouveau driver the crashing still occurs.

I've updated my NVidia driver to the latest using the PPA and OBS still keeps crashing, mind you this is on a fresh installed version of Kubuntu Linux.

Can anyone help me figure out how to fix the crash, it is really annoying that the entire system goes down.

Userspace applications should never cause the system to freeze, crash or reboot. In worst case the application should exit or crash. This either sounds like a faulty driver or a general hardware issue. Did you try to track cpu/memory utilization while running? Maybe something extraordinary happens before the reboot?

Well this only occurs after I switch to using the NVidia driver, so I was leaning towards a bug in the driver + OBS. I don't see this problem however until OBS is open.

I do notice the CPU gets maxed out when I have OBS opened and I am watching video. So it could also be something with OBS pushing the CPU load, which is just at 60% without OBS opened when watching videos.

It can't be memory as I have tons to spare. Not to rule it out, but if it was some hardware issue I should have see this kind of crash already occur with general usage, but only happen when OBS is open.

So it does happen with nouveau driver too? Also memory not being enough should be handled by the OS. It may be faulty though which may be a problem. But 60% CPU in idle sounds quite high too imo.. Did you check which process take up the CPU? Is it OBS? Some other? Where is 60% in OBS indicator? in top?

It does not happen on a fresh install with nouveau, which however doesn't seem to keep up with simple screen capturing. The problem happens only after I install the nvidia driver, even then if I switch back to nouveau my system will crash.

Most of the load is coming from firefox when watching youtube, obs in idle seems to be taking 8% of the CPU.
