Hello,
We had a Server 2012 R2 crash and not sure what caused it.
ntoskrnl.exe+1554a0
Attached is the memory dump.
I looked it up and came across forums on here asking if anyone else has a dump file to be analyzed, just open a thread and ask.
So here is it.
Nothing has changed to the VM since this has happened.
This is not a Microsoft support forum. Unless you have specific evidence (or strong reason to believe) this is related to VMware, you're better served either opening a support case with Microsoft or asking on a Windows Server focused forum.
After further analysis of your dump file, here's what I was able to get.
