Question find history of a job killed by "kernel: Out of Memory: Killed process"


During a long/few times a calcul's server not responding.

Anyone can't logging
Anyone can't execut command (top, ps, ...)

After in the /var/log/messages, we can see :
Sep 20 11:28:36 cluster-b kernel: Out of Memory: Killed process 16322 (Transp_image).
Sep 20 11:28:40 cluster-b kernel: Out of Memory: Killed process 10121 (rech).
Sep 20 11:28:41 cluster-b kernel: Out of Memory: Killed process 8045 (visu).
Sep 20 11:28:45 cluster-b kernel: Out of Memory: Killed process 25647 (Transp_image).


I wish know for each process killed :
- the owner of the process
- the memory usage of the process

It is possible ?? a file containt this information ??


With this, I could bactrack the binary's problem (in fact i suppose that the kernel kill the biggest use's memory process)



Thank you for your help and your idea ...

ps : for the futur, i could run a script that log the activity but i supposs that it exist another solution.
ps2 : "sar" don't run

If you can't add more memory, a "no cost" option is to add more swap space. Might only delay the situation.
If you can't/won't run "sar", try running "top" in batch and writing it to a file - say every couple of minutes. Will at least give you a bit of history.

Not of it's memory usage that I'm aware of.
