Thanks. If you are going to give us more RAMs, I am not going to refuse :-)

The last time this situation happened was last October. I don't think I 
looked into syslog back then, but the failure mode was quite similar, so 
it's probably the same cause. I don't know every twice a year qualifies 
as "OOM'ing a lot".

I just finished adjusting oom_adj for those two daemons.

We do no track VM memory usage at all. If you have an infrastructure to 
do that, your adding this machine to your setup would be greatly
