Hi all- I have been doing CICS programming for many years and believe it or not heard this term SOS for the first time today. I guess I have been lucky.
Anyway we were performance testing a CICS web service and the region just became unresponsive and had to be recycled. And the CICS admin said it was an SOS issue.
The program had performed well in the prior environments.

I was just wondering if it could be because the program underpinning the web service has a large-ish WS, just over 2.5MB. I say it is large because I looked a a number of our existing regular CICS transactions and none come even close.

The stress testing team were simulating a scenario with 25 active users submitting enough requests to mimic a peak production load of about 40K requests an hour- would it have caused this SOS scenario?

FWW we're on CICS 3.2 and the region under consideration has 130MB in 31bit storage
