Hi, I have troubles with xend crashing : (xen 3.4.1 - Kernel 2.6.31-rc3). Xend is working perfectly for some hours, then crashes. No logs, except in the dmesg : How can check what's wrong ? Regards, Here is the dmesg log : [68386.101572] INFO: task xend:19865 blocked for more than 120 seconds. [68386.101670] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
