Hi,
We're running several OpenBSD 4.6 VMs under VMWare ESX 3.0.2 52542, and
are seeing random panics with very similar panic messages once every
fortnight or so.
The kernel is GENERIC, but with vmt0 (VMWare tools driver) uncommented.
If anyone could shed any light on this, I would be very grateful.
A couple of examples...
VM 3:
----- panic message
