I will be sending in an slip dump of the 071 abend and logrec Macy's is running z/os 2.1. xmanager is at 19.0

Environment

z/os DB2

Cause

The problem is the stopping of the Xmanager address space with a S222 command.

Resolution

The Xmanager should be stopped in a control manner. Here is a link to the documentation on Stopping Collections. Canceling with a S222 can have unpredictable results.
There is a Common Services PTF RO91550 you can apply which should stop the S702 abends.
