CHECKREGIONLOSS parameter

IEF093I INITIATOR TERMINATED DUE TO REGION LOSS

Explanation: When ending a batch job, the initiator/terminator found that the maximum possible region size had decreased by more than the amount specified on the CHECKREGIONLOSS parameter in parmlib member DIAGxx. See z/OS MVS Initialization and Tuning Reference for more information on DIAGxx. The initiator will terminate to avoid abend 822 in a subsequent job that was selected by this initiator.
System Action: The system ends the current job normally. The initiator in this address space will be ended and restarted in another address space.
System Programmer Response: If desired, a dump can be obtained by setting a SLIP trap which specifies MSGID=IEF093I and rerunning the job which caused the problem.
