Sometimes we experienced an interruption of the jobs status update procedure for a specific user in Liferay on Glassfish installation of the GridEngine.
The problem could be due to a some libraries conflicts.
We shoud verify if the problem persists in Liferay 6.1
This problem should be fixed in GridEngine v1.5.1 that isolate the GridEngine from Glassfish.
It will be verified when GridEngine v1.5.1 is installed in production.
