I have 6 servers at soyoustart.com some windows 2008r2 machines, on different nodes, stops responding randomly (even they seem to bu running) and if I try to reset or stop it does not respond either.
Each time I have to reboot node.

Error I see when I try to start after trying many times to stop, I get following errors:



Code:
