Periodic crash of Windows Guests on Linux Host

[David]

This has been going on for a while and it's somewhat sporadic, say once a month, that this will happen. I have 3 guests running on an opensuse 11.4 host. The host has 8 GB of ram with 4 AMD cores and I have roughly 6 GB in use at any given point in time (free -m will typically show between 1.7 and 2 GB of ram free under buffers/cache). I also have 5 GB of swap available for use by the host and this is basically unused (maybe 30k out of 5 GB).

One of the 2 windows guests on the host will crash periodically. I don't believe that it has ever happened with the linux guest. Now, this latest time, the guest (SMP install) with a cpucap of 4 and limit set at 80%, crashed while just sitting there. I had rebooted it about 3 weeks ago and it was just sitting there when it crashed.

I start this guest from the command line using nohup and have this output as well. Another strange thing is that the nohup output appears to have more information in it than the log file. Anyway, I'm attaching all of it in the hopes that you can tell me what is wrong.

I have searched through the forums and don't see anything like this.

Nohup output file.

This contains the nohup.out, .vbox config. and vbox.log file.
