How to debug out of memory kill child issue

I keep having my 1 and only VM get shutdown due to an out of memory issue. I don’t know how to debug this to find the root cause. Can anyone point me into the direction of this? Here is a segment of my log that shows where the error occurred. 192...88 is the IP of my VM, before that you se the “out of memory”. I don’t know how to find out which docker container, if it is a docker container that is hogging all the RAM enough to shut down my VM.

 

On another note, this is why i was wanting to setup some notifications for unRAID to be able to send me information on when RAM or CPU is maxing out so I can go log in immediately and see what is going on. If anyone has pointers on this it would help too.
