Why is the process shutting down on the VPS?

Question

System administration

Shutting down process on CentOS 6 VPS. What is it and where to check?

Answer 1

OOM-killer kills him, for sure. Check - if almost all memory is full, it will nail

Answer 2

If the program whose process is being terminated implies the mode of logging debugging information, then it is better to enable it. I always do this. Logs sometimes write a lot of interesting things.

Answer 3

Run cat /proc/user_beancounters on the machine
After the process crashes, repeat the command and compare the counters of the rightmost column. If they haven't changed, it's in the program. If changed - you do not have enough container resources.
