Well, hunting through /var/log/messages I see:

I dont know if those db errors are due to the processes being killed or 
if they might be a cause of the oom.

Still a mystery why the oom.  If we need more memory, I can allocate 
more to our guest, which has 64GB right now and using half of that 
currently, but jira is down.
