We have 4 Windows servers 2012 r2 running on a ESXI 5.5.0 1623387.
The hardware is HP Proliant DL380p gen8.
3 of the Windows servers, run fine, without problems.
We do however, have problems with the last. It is used as a terminal server for our customers, running maximum 15 users at the time.
It has been given 16GB RAM, 16 cores (4 cpu's with 4 cores each), 60 GB harddrive and a VMXNET 3 NIC (as the default NIC has problems on 2012r2 servers).
The server crashes all of the sudden, we can't seem to find a reason for it. It is running the same hardware as the others, so it seems wierd.
i've attached dump files.
