You indicated that it depended on the setting for JOBDEF INTERPRET=. What is your JOBDEF INTERPRET= setting that the problem occurs under? Also does the loop occur if one defaults to DSENQSHR=ALLOW on the JOBCLASS setting? Just curious.

The loop could occur with any batch job,but not every batch job. IBM has found the loop in module IEFNB903 and are looking at it. The looping condition only occurs if DSENQSHR is enabled for the job. In our case the JOBCLASS definitions had DSENQSHR=AUTO. Once we changed it to DSENQSHR=DISALLOW the problem no longer occurred.
