Today, I caught it in a reboot and on the console it said it was shutting down the CPU's, like someone had hit control-alt-delete on it (the same message)... But there is no keyboard attached to it, and nobody was logged in. This happens randomly every 3-20 days (no apparent pattern). I originally thought it was the 3ware controller causing it, but there was no correlation. I tried installing 'mbmon' port, but when I run mbmon -d I get: mbmon -d InitMBInfo: Operation not permitted This program needs "setuid root"!! The SUID flag is set, and I'm running it from root. I am wondering if there is a possible power supply issue, or something like that. I swapped the PS some time ago for a bigger one, but that didn't change anything. If anyone has any suggestions on how to get mbmon to work I'd love to hear them. The MB is GIGABYTE GA-M61P-S3 GF6100 AM2, which uses the nforce4 chipset. I'm not even sure if mbmon works with that newer chipset or not. I'm suspecting power problems further upstream (at the data center) but I have no way of knowing. There doesn't seem to be any coorelation with usage either, so I'm kind of stumped. Any suggestions on what to check next?
