Hmmm...
Cacti woldn't think so: the graph about swap space is plain flat (round 
0%, by the way); of course it could have risen so fast that it reached 
100% between two consecutive polls, but I doubt it.

Besides, why would the system crash for such a reason? I'd expect 
application failing, not the whole kernel. Am I wrong?

SOB! I hope not. RAM is fine, HDs are SAS RAID with a good contoller 
which should have detected failures...
What else can I check?

Right now I've only had this crash (and hope no other will follow). In 
the worst case, I'll take notice.

I appreciate your interest anyway.



  bye & Thanks
