Enabling DAG crashes Exchange Server and it's Host

Strange issue here, Im setting up DAG for Exchange 2010. Both Exchange servers are running SP3 rollup 9.

Exchange Server A has been in production for several years with no issues.
Exchange Server B is a brand new virtual machine running on Hyper-V Server 2012 R2.
Exchange Server B works fine when being put to a load, however when DAG is setup and its seeding the 200gb database Exchange Server B crashes and brings the Hyper-V Host with it. Both reboot.

I can copy a 800gb file from the network to Exchange Server B and it doesnt crash.
I can copy 100gb of log files using 32-threads and it doesnt crash.
But the second I turn on DAG, it crashes.

I've checked the logs and can't find anything related. I did find an article (https://support.microsoft.com/en-us/kb/2629777) that is very similar in issue but the resolution points to an old update, that this server has.

Any Ideas?

Any errors in system or cluster logs. You might need to enable full memory dump to find why it is crashing. It looks to me resource issue. Suggest you to call Microsoft.

Hoping you are using fixed disks for Exchange Mailbox DB storage.

Update: it turned out to be a bad hard drive. I found the bad hard drive via Dell Open Manage. Logs said media error.

Dell replaced the drive and now everything is fine.
