Hi, I had a server crash badly on me, the dmesg was totally full of exactly this:
unregister_netdevice: waiting for lo to become free. Usage count = 3
I found another post on the forum from last year about this but it doesn't sound like my problem. I had to physically reboot this server, and the load spiked from 4 to 1000 within a few minutes of hitting the problem.
HW: 2x quad core xeon 5345
32GB mem
2.6.18 + patch-ovz028stab039.1-combined
32bit kernel
I am going to set up netconsole in case there is more info the next time it crashes. Can anyone tell me if this error message means anything specific to the crash?
