Out of Memory Crash of Game and Steam

[errantmind]

Sometimes my entire game (and steam!) crash with an out of memory exception while spectating games. I haven't had it happen while playing a game but that could be coincidence. Note, I've been using steam since 2003 and never had it happen in any other game. I'm playing on Linux with Proton on a system with 64GB of RAM and 12GB of VRAM.


The steam console output is as follows:

I've been getting this bad too on Arch Linux. My first game today was completely unplayable, with my game crashing every two minutes. My game quality is as low as it can be without looking so bad it's unplayable.

Can we just get the official linux build already? This proton layer is rough valve.

Bump. This is still happening

What process is trying to allocate the memory? Have you tried setting static (expanded) limits? https://unix.stackexchange.com/questions/44985/limit-memory-usage-for-a-single-linux-process

Steam is trying to allocate the memory. When Deadlock crashes, so does steam. This only happens when playing Deadlock and not any other steam game (10k+ hours in steam games), so I highly suspect it is Deadlock related.

It is a bug and I'm not going to try to work around it by setting expanded limits. I have many applications allocating 10s of GBs of memory on a daily basis, this kind of workaround should not be needed (assuming it even works).
