Have you searched for similar hyper-v crashes with plain debian? Since UCS is based on debian I would expect other reports if there is a compatibility issue with hyper-v.
Do you have other things running under hyper-v on the same hardware and are they running ok?
thank you for telling me that it is debian, configured it now after best practise for debian, will report if it still gets stuck.
Problem was/is that the network interface lost connection and in the Hyper-v Terminal was no interface… as the network connection was lost every time i also clouldnt coonnect to it via putty…
another problem are these error messages at the time… :Connection to module process failed: udm
