Evening,
I'm not a big guru in kernel panic analysis but the parts:
Modules linked in: md5 ipv6 autofs4 i2c_dev i2c_core uhci_hcd 3c59x mii floppy ata_piix libata dm_snapshot dm_zero dm_mirr or ext3 jbd dm_mod 3w_xxxx sd_mod scsi_mod
Aug 15 23:01:28 mydomain kernel: Process ossec-syscheckd (pid: 11762, threadinfo=c48f8000 task=c75a27e0)
may point to that ossec update.
regards Jordi

Hello all. I have been running running centos 4.5 final for some time with any problems. Been running great, until today. System was frozen and /var/log/messages showed:

I don't understand the meaning of all of this? I'm trying to find the cause of why my system froze or crashed. The only recent change ( a few weeks ago ) that I did was an upgrade of ossec from 1.2 to 1.3. Does this log show or hint to the cause of the problem?
Thank You
Noel
