Issue:
We encountered multiple S0C4 abends in module SHRXSUF0 in IMS at the same time as a U0002 abend in a BMP region. The IMS system crashes but is restartable.

The BMP region abends with the following U0002 abend

The IMS region issues multiple S0C4 abends:

Cause:
The U0002 abend in the BMP region is a pseudoabend which is forced when the IMS region terminates.
Resolution:
Has the DBD recently been amended and regenned? A possible cause of this problem is an error in the associated DBD.

Correct any errors in the DBD and then run ACBGEN.
