Help Please - my previously stable system has become rather unstable!
I was running 4.6.1 for a while, and all was stable. The box had about
40 days uptime since going live. I then moved up to 4.6.2 on Sunday
afternoon, since there seemed to be general concern over stability with
4.6.1.
On Sunday evening at 22:21 (about 3 hours after completing the upgrade
from 4.6.1) the box crashed and restarted of it's own accord. And it
just did the same again about half an hour ago (11:46 Tuesday).
I have included extracts from /var/log/messages below. The significant
part seems to be:
---
Fatal trap 12: page fault while in kernel mode
---
Unfortunately this means nothing to me :(
I notice that the "current process" on these two occasions is NOT the
same (rateup on Sunday, perl today). But I have no idea whether that is
significant at all.
Any advice would be VERY MUCH appreciated! Also, please let me know
what other info would be useful in helping resolve this problem.
