Sometime, one of the machines does not want to start permanently and I have to reinstall/restore it. This problem comes for me randomly, but maybe there is a trigger. I've tried to follow: http://xen.1045712.n5.nabble.com/2-6-32-27-dom0-BUG-unable-to-handle-kernel-paging-request-td3323011.html and raise /proc/sys/vm/min_free_kbytes, but it did not help.

Can it be a hardware problem with RAM ? Regards Slawek
