The following could explain what you are seeing but is based on a fair amount of guesswork : (1) ISV code using some sort of BPX* service that results in new ASID being created to perform the work - one of those "*OMVSEX" chaps (2) ISV (or IBM) code that runs in the new ASID wants, with good reason, to setup a ASID-level RESMGR routine to clean-up when the BPX-thing terminates. (3) RESMGR code uses some sort of pointer to a TCB in the now-terminated ASID (4) TCB addresses *can* be similar in different address spaces (obviously they are not the same thing) (5) RESMGR routine has (for years) been processing the TCB address passed to it and finding a valid address in ASID(0001) - hence there has been no abend (6) Something has changed in R12 that has made that TCB address not valid and the bug (that has been there for ages) now suddenly bites.

It's a monitor tool. I can't say more. We continue to use the product under a "permanent use" license that we got many years ago. But we dropped the support license in order to save money. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
