Hi,
I've got a fileserver that runs Centos 5.2. It's been stable otherwise stable for maybe a year or more, and now it's crashed three times since Saturday. The first two times the computer was completely unresponsive, and there was nothing on the console, and nothing in the logs. I was beginning to suspect hardware, (esp. RAM, PSU, or maybe a failed fan) Last night it locked up again, but this time there was something in / var/log/messages. (see below) So far my searches indicate that increasing to 8K kernel stacks would fix this. The server has a couple 3ware SATA RAID cards, and I'm running xfs. The server does nightly disk to disk backups of a few dozen workstations. The server does always seem to crash overnight. If the problem really is in the kernel stack size, it's odd that it just started all of a sudden. I thought I'd post here before I looked into compiling a new kernel with 8K stacks. Thanks for any advice!
Did you check in your server hardware logs (if it has some; like IPMI?)?
