Explanation

The system encountered recursive program checks. Usually, this is the result of an overlay of a critical system control block, such as PSA, ASCB, SGTE, or PGTE.

System action

The system enters a non-restartable wait state.

Operator response

If the system programmer requests a stand-alone dump, obtain one. ReIPL the system.

System programmer response

Do the following:
  1. Ask the operator to obtain a stand-alone dump.
  2. Determine the control block that has been overlaid and the module that did the overlay. In many cases, the last program to be dispatched on that processor caused the overlay. The last program dispatched can be determined from the system trace table.
  3. Search problem reporting databases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Because of the possibility that a hardware malfunction contributed to this problem, you should also contact hardware support. Provide to the IBM Support Center and to hardware support the stand-alone dump.
