Fix Common Problems: Out Of Memory errors detected on your server

Featured Replies

Been experiencing intermittent server crashes and this is really my only clue that something is wrong. Syslog doesn't seem to show anything relevant. I tried putting the hungriest containers on a diet, but it's still happening. Seems to only happen overnight when I have parity check running which is almost every night since the crash triggers another one to start when I boot.

Thanks in advance for any help

Bump...anyone?

The killed process was the Sonarr container; it consumed ~4.9 GB, try limiting its RSAM usage.

Thanks, I've done that and now I'll wait and see. How can I see which container it was if it happens again? I've been looking in the syslogs which didn't appear to show anything like that, at least to me.

Search the syslog for "out of memory", it typically identifies which process was killed, and most often that is the one that was misbehaving.
