A symptom dump has been produced for my GSS STC.           

When I looked at GSS joblog, I can see a S502 abend:

Why do I have a symptom dump for GSS and a S502 abend? 


CA Common Services R14.1 - Supported z/OS releases -


The S502 abend indicates that the EVENTS table is too small.

The CA-GSS dispatcher is constructed around the z/OS EVENTS facility.

The EVENTS table must allow a slot for each pending (unprocessed) event.

Depending on dispatching priorities and selected options, the EVENTS table needs room to buffer deferred work.

An S502 abend usually indicates an EVENTS table that is too small, you have to increase the EVENTS value in your RUNPARM member.
