Hi,
We have a number of Debian woody servers, mostly Intel kit. One of our P4 boxen decided to reboot itself twice over the weekend. last -x:
runlevel (to lvl 2) 2.4.20 Sat Jun 12 08:04 - 10:12 (1+02:07) reboot system boot 2.4.20 Sat Jun 12 08:04 (1+02:07) shutdown system down 2.4.20 Sat Jun 12 07:50 - 10:12 (1+02:22) runlevel (to lvl 6) 2.4.20 Sat Jun 12 07:49 - 07:50 (00:00)
No previous logins within hours of this. syslog shows eth0 ran out of resources, followed by a regular cronjob (very memory intensive), followed by out of memory errors, then a switch to runlevel 6.
how much RAM and how much SWAP do you have? How about spave on /tmp and the other partitions?
Kernel may have bugs, but its been running otherwise fine for months. I wonder what may cause the kernel to switch to level 6 without user intervention?
Which bugs? Which filesystem do you use?
Regards, Mathias
