[StarCluster] jobs on slave nodes disappear

[liang cheng]

Greetings !

I created  a star cluster on EC2 and use qsub to submit jobs. It used to
work well. From this afternoon, after I requested for additional EC2
instance from Amazon, the issue comes out.

Only the jobs submitted to the master node are executed. Other jobs
disappeared just in no time.  Some diagonosis is as below. Any helps are
appreciated !

Happy New Year !
