Bill,
Thanks for the info. Had already looked at the system trace table
in the dump. The SRB had been dispatched. I found the IEAMSCHD entry,
then a bunch of timer pops, and then finally the 5B abend. The runchain
IPCS command showed me the error, I just have to figure out how I
created the error in the 1st place.

More SRB debugging hints:
The SRB routine may never have been dispatched, or was dispatched with a lot of
other higher-priority activity (especially SRBs) running. This would depend on
whether you SCHEDULEd your SRB as global or local and what other work was
running on all the various processors at that instant. Look in the system
trace to make sure your SRB was ever dispatched. And I believe that XDC can be
used to trace code running in SRB mode.

Subject: IPCS help needed
Looking at an SVC dump of my application. Dump was produced by my FRR
when the SRB that was running timed out. 05B abend. I set a timer when the
SRB initially kicks off.
The logic in the SRB is processing some data areas, working its way from
top to bottom in a linked/chained list of these same sized data areas.
The list in the dump has thousands of entries. One of two
possibilities. Either the linked list has an invalid chain ptr, and the code
is running in circles. Or, the list is good, and I just needed to give the
code a longer period of time to run.
My question. Is there a way within IPCS I can describe the data area
containing the chain pointer, and then run some kind of a command that would
run the list to determine if the list is good or not?
I'm in the IPCS manuals right now, but if its there, its not jumping out
at me. Any help would be appreciated.
