Assertion failed! error ...

[RA Cohen]

Not sure if this was sent earlier ...

Trying to diagnose a problem Windows 2012 Server guest which has been 
freezing up after 10-20 hrs.

Now I cannot get it to run at all and these appear in the FBSD 10.1 syslog:

Sep  4 08:00:02 hbvserv2 kernel:
Sep  4 08:00:02 hbvserv2 kernel: !!Assertion Failed!!
Sep  4 08:00:02 hbvserv2 kernel: Expression: RT_SUCCESS_NP(rc)

Sep  4 08:00:02 hbvserv2 kernel: PGMHandlerPhysicalRegisterEx 
000000015ae50000 failed with -1701

Do I have a hardware issue? Corrupt files somewhere?

More background:

zfs on root underlying all
one pool: zroot
two mirrored spindles (by gpt/zfs)
two vms:
   a) lightweight fbsd machine running samba acting as pseudo domain 
controller
   b) Win2012 Server consisting of three vmdk files - one os and db, the 
other two simple data

host=DELL PowerEdge 1750 w32gb ram dual 4 core proc

The fbsd vm and host stay up and running through all the issues.

Thanks in advance,
