I'm trying to debug some issues with my Mac. This machine is used as Continius Integration server. It stops responding from time to time. I think it could be some software issue, sins machine is working (so i.e. it's not kernel panic) - that is when I go to server room I see login screen and I can move mouse. Unfortunately I can't login neither directly nor by vnc or ssh.
There is nice tool that help debugging this type of problems - aTop. It's like top but with history. Unfortunately it's Linux only software.
Is there any similar tool for OSX?
