One of my RHEL 6.3 build on vm raised an alert virtual mechine cpu usage. I tried to connect to the vm using putty but the connection could not be established. There was no packet loss from ping. At last I had to reboot the vm and then everything was normal.What was the problem and how can I find it?
debugging: new ssh connection could not be established but ping was ok on RHEL 6.3 (high cpu usage)
