SGE execute daemon

If the queue instances for a running slave node are shown as having state "u" or "au" in the output of qstat -f, or the load_avg ("load average") field is shown as "-NA-", it is likely that the SGE execute daemon on that node has crashed. To find out if the daemon is running, look for a process called sge_execd in the output of ps aux. If this process is not running, it can be restarted by executing the following command as root:

/etc/init.d/sgeexecd start
