I''ve encountered this frequently due to high io load. If you have monitoring of load and io, did you see anything happen just before these errors started in the logs?

I am not sure its due to high load in my case since there is still no high load in server. I didn''t run any program that have high load and no client that accessing this server. I am suspecting the hotplug script. In my xend.log here is the logs : server1@server1:~$ sudo tail /var/log/xen/xend.log [2013-03-13 13:04:51 1983] DEBUG (DevController:144) Waiting for 51712.
