[2023] [Linux] Crash due to memory exhaustion (OOM) after using 14GB memory

From what you say this is either a game bug, or your machine is filling up memory and swap file with other stuff. If you increase that swap file to say 16gb as a test, does that help?

If not I suspect this is a game bug, perhaps confined to Linux, so would need to be reported in the Bug Reports forum.  

Please add your details to the Bug Report linked above. Thanks!
