Re: jobs on slave nodes disappear

Thanks for your reply. There's no error log nor output log even when I use
"-e" or "-o" option.
I created a cluster with one master and 10 slave. I made a minor change on
the master node and use "starcluster createimage i-xxxx AAA BBB". "i-xxxx"
is the instance id of the master. After I got the ami-yyyy, I run
"starcluster start ami-yyyy". I found all jobs submitted to slave nodes are
finished instantly, as you see in the log I sent earlier. The jobs in
master node are run normally.
I haven't used "restart" command but will give it a try.
