[Xen-users] windows 2k8 rebooted by itself several times, perhaps dom0 heavy load?

Hi!

I have a Win2k8 R2 running under my Gentoo dom0.

Sunday night I started compressing a large file on the dom0 linux, and next day I saw that during the compression period, the Win2k8 restarted several times.

Logs:
xend.log:

Issued domain 15 reboot

This is very frustrating, because the server is a live server, and reboot is not preferred just randomly. And I must say that PV drivers are installed too, it didn't even reboot nicely (with shutdownmon) as I can make it reboot manualy.

I have Xen 3.4.2 running with 2.6.32 kernel.

What can I do to avoid this reboot? It is ok if it slows down, but it shouldn't reboot.

Thanks in advance!

Regards,
Daniel
