We migrated one of our systems to z/OS 2.5 last weekend and immediately started
getting a hard loop during job conversion/interpretation either in the JES2CIxx
or INIT address space depending on your JOBDEF INTERPRET= setting.
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.
We are now seeing this in our z/OS 2.5 JES2 environments. The loop is in
IEFNB903.
Your IBM-MAIN posting was from way back in October. I assumed this would
have been fixed by now.
Did IBM take an APAR?
