Host is Windows Server 2008 R2 server core. It uses Hyper-V. There are 4 guests machines. After months of stability I get this "Paused State" error. After clicking resume, they seem to run a few seconds and return to paused state. The only way out is to restart the server and I don't like to do this to a production machine. I read some articles on-line and the recommendation is to free up space in the cluster drive. I am not sure if this is correct. If so, can someone provide a "how to" for the core server. Thank you.
