Hello,
We are experiencing an S0C4 abend after upgrading to z/OS 1.13. The
application is known as KBMS, has been unsupported since 2000, and is critical
to the business. We are working on a replacement, but full implementation is
still several months away.
We have experienced problems with the application in previous upgrades, but
were able to address it by re-linking some of the programs (we do not have the
source). Unfortunately that approach is not working this time, so I'm hoping
someone can explain what might be happening and possible solutions.
Thanks in advance for any insight that is provided.
Here's some detail pulled from Fault Analyzer: (note, only copied events 1-9,
10-128 are recurrences of 6-9)
