Run netstat, is commd making a lot of connections to itself?  If so, you
should check if any of your nodes has its hostname set to 'localhost'. 
I had a node like that.  It caused commd to open connections to
'localhost', which meant it was talking to itself and ended up running
its own CPU usage up to 100%, and causing timeouts when trying to
connect to the master.
