Thanks to all, we found the developer had a JCL problem and a logic problem (see above).

To test the syncpoint, I created a client app from Windows that set Syncpoint. I added a routine to do a memset with an invalid size, which abended/halted the program. (I left out the MQCMIT call on purpose). My program ran as advertised, and the messages rolled back.

We also discovered that the developer was using Xpediter (CA) debug tool to walkthru the code. It seems the Xpediter will issue a graceful disconnect from MQ (thus causing an explicit commit).

Anyone ever seen this issue with Xpediter before?

Thanks again, TJ
