Hi,
Our box crashed with the following oops, though it continued to live for a couple of minutes at the end it freezed completely.
All disk-partitions contains ext3 with the following mount options:
/dev/ide/host0/bus0/target0/lun0/part1 on / type ext3 (rw,errors=remount-ro) proc on /proc type proc (rw) /dev/ide/host0/bus0/target0/lun0/part3 on /home type ext3 (rw) /dev/ide/host0/bus0/target0/lun0/part4 on /var type ext3 (rw)
The crash seems to be related to a mail loop, the MTA running on the box is postfix. The box has a single processor.
The kernel is patched with the following patches:
- netfilter submitted patches (those submitted at 2.4.22pre7) - our tproxy patch (version #18) - freeswan - the AIC7xxx driver from people.freebsd.org (it is not used in the box) - 2.4.21-ac4
