If processes are killed by OOM Killer, there's a prominent message to
that effect in the system logs (/var/log/messages or some such).
Search for "oom" (IIRC) in the log.

No such thing on any log. Grepped for both "oom" and "IIRC".
No new crashes happened after I started using -j 16, and since I don't have time nor experience to debug this I'll leave it alone for a week or two and start getting to know the kernel better and then try debugging it again.

Thanks for the help.
