Walt... Thanks for asking questions. I will answer you questions as best as I 
can. 
 
Does that duplication include number of CPs and processor speed? I have seen 
test environments that were setup as single CP, which does little to help debug 
problems related to multi-tasking or -processing. 

A: No! We don't have a test environment that can duplicate their environment in 
that detail. Our test environment is running under VM on a 2827, I will check 
if we can specify how many CPs. I will check with the client as to their CPU 
types, number of CPs, and LPAR layout.

How many simultaneous copies of your batch process were running, given that the 
client could have dozens or hundreds of address spaces writing SMF records? How 
much multi-tasking within your batch process did you have, in case the issue is 
related to multi-tasking rather than multi-processing?

A: I only ran one one batch process at a time but the normal SMF processing was 
happening at the same time. I will run another test.

How did each of your batch processes pass the records to the exit? And which 
exit(s) did you use?

A: The called the exit directly passing the record in register 1. We use the 
same exit for IEFU83-5.
