This server (FreeBSD 5.4 RELENG) is crashing once a week or more since
5.4 (maybe before).
It may be related with a full filesystem:
I'm using snapshots on this server (using
http://people.freebsd.org/~rse/snapshot/), and crack has occured after
(~30mins) a snapshot that fills up to 100% the filesystem.
Attached the dmesg and kgdb logs.
I'm not so hacker, but hope that it can help to resolve this bug.
