We are running UE4.27 game as a linux package in a container. The game fails around 10% of times with the below issue. I wanted to know what could be causing this crash.  
If there is any to fix for this issue.

Also, At the time of crash we had 3 GB free of 16 GB. CPU was also not at its peak

My colleagues imported plugins for pixel streaming, after the game launched in Linux for several minutes, it just crashed.
