Im going to replace a server with a new one...
In the logs I find
Nov 22 02:20:54 sv01 kernel: Uhhuh. NMI received for unknown reason 31 on CPU 0.
Nov 22 02:20:54 sv01 kernel: Do you have a strange power saving mode enabled?
Nov 22 02:20:54 sv01 kernel: Dazed and confused, but trying to continue
Oct 8 04:17:03 sv01 syslogd 1.4.1: restart.
As you see, there is a false date Oct. 8
NMI seems to be watchdog. But the error 31 may be a faulty memory
The end of the log says
Oct 8 04:19:47 sv01 kernel: usb 1-1: USB disconnect, address 2
Then a reboot
Nov 23 14:11:03 sv01 named: *** POKED TIMER ***
and the server is again running.
Any ideas to what to think seeing these logentries? I checked other logs but no relevant lines in there.
Anyway, Ill pick up the new server today, restore the domains and replace the hardware tomorrow or so.
