    Hello everyone,

    I'm new to analyzing crash dumps and so far have come up with that it is likely I had some sort of memory problem or VHD issue with vhdmp.sys.  When it crashed there were many servers re synchronizing with their replicas which is hosted on a SMB 3.0 share on a server 2012 standard edition file server.  I know there likely was a lot of disk I/O and there are 12 VMs on it, 3 of them are rather big ones server about 2,000 people for video streaming and delivery.

    System Info:

    Mobo: SuperMicro X9DRI-LN4F+ Intel Xeon DualProc

    Proc: 2x Intel Xeon-SandyBridge E5-2690-OctoCore

    Memory: 8x Samsung 1600 16GB DDR3 2Rx4 [16GB]

    Raid Controller: Adaptec 5405 Z (1b4611d360f)

    Battery : Adaptec ZMM-100CC

    OS SSD: Intel x25-E Extreme ( SSDSA2SH064G1)

    Raid 50 Array for Hyper-V:

    10X Seagate ConstellationES.2 ST33000650NS [3000GB]

    10 gbps fiber nic:

    SuperMicro AOC-STGN-i2S SuperMicro 10 Gigabit Port

    Power Supply: 2x     SuperMicro PWS-920P-1R 920W (one is a redundant power supply )

    Here is my !analyze -v output from the debugger:

    Did you ever figure out what was causing your crashes?  I am running Server 2012 (standard) with Hyper-V installed, but I am not currently using Hyper-V.  I was using it (Hyper-V), but thought it was causing these crashes, so I stopped all VMs and moved to another Server.  I continue to get these crashes after stopping all VMs.  I have had 4 spontaneous crashes in the last month.
