[GE users] How to remove "E" in the queue status

The "E" error state usually means that a job died in a spectacular  
manner (possibly taking down the sge_shepherd with it).

SGE persists the E state until it is manually cleared, to prevent a  
"black hole" effect whereby all your pending jobs drain into a  
potentially "bad" machine and all exit quickly with some type of error.

The first thing you should do is examine the cause for the E error.  
If this was a transient error or something that you do not think will  
repeat then you can clear the error state. It is not good to clear  
the E state if it is just going to come back again.

The clear command is "qmod -c" and you can clear your whole cluster  
with " qmod -c '*'  "
