I have a simple Tyan server with RAID1 on a 3ware 7002 that has been running updated Centos 5.1 for almost 3 weeks with no problem, it runs low-traffic Apache/PHP/mySQL and vsftpd sites exclusively - last night it crashed. The console showed something about a process named 'php' and gave a process id with the panic message, but that's all I can remember. Hard-rebooted and all was well...
Then about 55 minutes later I was logged in with ssh and it froze. Another fun holiday trip back to the datacenter. This time I brought a camera, but found a message totally different - this seems more like a ext3/disk problem?

the logs contain nothing unusual. I have set up a script to do a vmstat/ps dump every 10 minutes. Anything else advised by this kernel dump or places to look?
Thanks much- Sam
