Usually what I have done in the past as to not disturb current running 
jobs on the exec hosts and the qmaster computer is to either delete the 
job that is causing the problem and then clear the error state 
specifically on that exec host, along with the process ID of the job.  
Sometimes this fixes the problem and fixes the queues.  Other times I 
have had to just simply restart the sge_execd service.
