Today i restarted one of my Hyper-V servers and when it came up again i saw that most of the machines was stuck in a starting state.
I tried stopping and restarting all three of the Hyper-V services but with no luck
I ended up inside taskmanager and saw a lot of Virtual Machine Worker Processes (vmwp.exe) and that many of them was using a supiciusly low amount of memory.
I started to kill of some of them and suddenly all of my machines started up from their saved state
Strange, i hope this helps someone else
I’m not sure how i can explain this error to Microsoft – i’m not sure if i can reproduce the error.
