Random BSOD's on Windows Server 2012 R2

As of late I have been getting random BSOD's on a Windows 2012 R2 server. It seems to be happening once a day, and can not pinpoint exactly why. Any help with this would be amazing! I have done a registry clean, and also updated all drivers. It seems to have started on the 28th of September out of random and I can't pinpoint anything that was done to the server that day or the day before to warrant this to be happening. Here are the memory.dmp and the minidump.

ANY Help is greatly appreciated!! Thank you in advance!

They mention this bug happening every 24 hours, which perfectly matches your description. They also repro an identical stack trace. So I'm pretty confident that this hotfix has your name on it.
