Case1 A standard abend is issued.
Case2 A pseudoabend is issued.
See message DFS2450I in this manual for additional information. If message
DFS2405I was not issued, the amount of storage specified in the PIMAX
parameter may have been exhausted. Increase the size of the PIMAX

Messages and Codes.
System Action: For Case1, the IMS control region terminates abnormally.
For Case2, the application program terminates abnormally.
Programmer Response: For Case1, contact the IBM Support Center for
assistance. For Case2, correct the cause by increasing the maximum storage
available for the ENQ or by decreasing the requirements for ENQs.
Master Terminal Operator Response: For Case1, none. For Case2, decrease
the system load by stopping the regions; then start the indicated SMBs and
PSBs. If a BMP is not taking checkpoints and has used all available ENQ
space, cancel the BMP.
