Explanation: The task has terminated abnormally because of a program check.
System Action: The task is abnormally terminated and CICS issues either message DFHAP0001 or DFHSR0001. Message DFHSR0622 may also be issued.
User Response: Refer to the description of the associated message or messages to determine and correct the cause of the program check.
You need to look at whichever message(s) were generated by CICS to figure out how to fix the problem. The fact that it's only happening in one region could be something specific to the region (i.e., the code is different for some reason, or the data is different for some reason).
