Hi Robert thank you for the update.
Sorry for the late reply.
I ran the coredump and it appears to be virtio network driver that’s causing
the crash. At least that’s what it looks like to me.
Let me know what you think.
Here is the output:

Greetings friends, I have a VM that crashes once every day or every other day.
There are no errors in the VM logs….it just shows that it may have lost power.
In the GZ I’m getting VM core dumps. Could someone point me in the direction of
the documentation or towards a tool that would help me analyze the VM core dump
to determine why it is crashing? This is a windows server 2008 r2 sp2 VM for
the record. GZ: is joyent_20151104T185720Z Thanks! John

GZ: is joyent_20151104T185720Z Hi John, So, the best thing to do would be to
run mdb on the core file. I would run something like mdb -e '::status;$C'
/path/to/core/file. If you can share those outputs, we can likely tell you what
happened and if this is a known bug. Please note that there have been many
important bug fixes and security fixes since that version, so I'd encourage you
to update, but we should make sure that this is root caused regardless. Robert
