We experienced an issue with a newly built Hyper-V 2012 R2 server running on Windows Server 2012 R2 Datacentre edition with all the latest critical and security and critical as of 23/06/2015. The server was built, setup with a number of virtual machines and ran without issues for a period of approximately 1 month. After approximately 1 month, the server started blue screening on a regular basis, no changes had been made to the Hyper-V Host.
The Hyper-V Host was setup on a Dell PowerEdge R730XD with 192GB of memory.
The Blue Screen error was: KERNEL_SECURITY_CHECK_FAILURE
The cause of the crash as per the original error was from the NT Kernel (ntoskrnl.exe).
We opened a support case with Microsoft to get the full memory dump analysed. After the memory dump was analysed, we were advised it was a known bug in Windows Server 2012 R2 identified 14th of April 2015. They pointed us at KB3055343 which resolves a issue with Windows that can cause inconsistent network interface data on the system.
After downloading and installing KB3055343 the issue was resolved.
