Some Uprocs, fail to be Submitted so they end in status Aborted, with the action Icon "Could not Submit".
The history trace is available.
The Job Log is created, but belongs to the user root and is empty.
A temporary file containing the environment execution variables remains present in the folder $U_TMP_PATH
When relaunching the Uproc, it usually works fine, launching it 5 minutes later, works fine as well.
Nothing can be found on /var/log/secure or /var/log/messages that explain why the "su" command fails to switch from root to the submission system user.
