Based on the datestamp of the crash the system is likely to have been 
doing a couple of pkgsrc builds in chroot environments.

I've got the crashdump from the failure so if someone wants additional 
information I should be able to get it.

If this has already been fixed let me know and I'll update to a new 
9.0-STABLE :)
