System Randomly Halts

[Henri Cook]

My system crashes almost twice daily. The machine stops pinging and acts as if it's been powered off, it takes a reboot from the datacentre to have it respond again. This is an issue that's massively affecting those of us using the machine.

This bug is very similar to other reports such as "Xen crashes under high I/O Load"

I thought it might be related to swap, as the system did seem to crash when swapping; I've taken my system's ability to swap away and it still crashes.

In the last instance I have 3 DomUs running and was performing a windows install on the 4th

I can't find any indication of an error in any of the system log files (at least not one that I spot) - my dmesg from the most recent crash is attached

This can be recreated; whenever I try to complete a windows XP install over VNC in a DomU - the dom0 crashes during its initial 'moving files into installation folders' stage. This is presumably a high I/O situation on a DomU which causes a crash in Dom0, i'm loading windows over HVM.

I'm fairly confident that if I simulated high IO (e.g. with a stress program) - the system would crash with no error message again and again. Please let me know if you require any more information or have suggestions on getting a meaningful error message

Is this symptom still reproducible in 8.10 or 9.04?
