------------------------


I'm able to reproduce this rather consistently in my 6.2u5 install.

If a an array job is submitted that uses a PE, and it has jobs dependant on it, the qmaster process will crash when the tasks in the array job are completing.

The messages log shows:

04/26/2010 09:27:57|worker|master|C|!!!!!!!!!! JB_ja_tasks not found in element !!!!!!!!!!

Restarting the qmaster just causes it to crash again. Sometimes there is enough time for me to fire off a qdel, but other times I have to manually delete the job directory in the
qmaster spool.

I have a copy of the spool directory of a job that exhibits this behaviour if that would help in diagnosing the problem.

We did some further experiments. It seems this only happens if the dependant job is also an array job that uses -hold_jid_ad to depend on the job using a PE. If the dependant job uses
jut -hold_jid, there is no problem.
