Error description
You are running CICS TS 5.3, with "Policy system rules" maintenance applied. You are repeatedly getting an error reported: DFHMP0002 A severe error (code X'0606') occurred in module DFHMPMO There is a corresponding trace entry: taskn QR MP 0606 MPMO *EXC* MPMOD_unlock_failed REGISTER_POLICY,Policy_Rule_Name,aaaaaaaa , 00000000,LMLM_P The message "MP 0606 MPMO *EXC* MPMOD_unlock_failed" is ouput by DFHMPTRI, based on the value of tid_mpmo_mpmod_lock_failed. This is set after a call to UNLOCK MPMOD (SHARED), in DFHMPMO. The lock is held EXCL. There is also an exception trace entry, showing an issue is with the PLIST: LMLM_PLIST: ** Decode of parameter list failed ** The LMLM parameter list is area 2 of the MP 0606 exception trace entry. It appears to contain character data including a partial timestamp (just a second before the dump). This APAR is being opened to investigate the looping behavior, which is responsible for the repeated DFHMP0002 messages. Additional Symptom(s) Search Keyword(s): KIXREVxxx

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: Message DFHMP0002 issued repeatedly for * * severe error x'0606'. * **************************************************************** DFHMPMO REGISTER_POLICY requires the locking of lock MPMOD, if either the lock or unlock fails the CICS region enters a loop issuing message DFHMP0002. This loop is only seen in CICS TS 5.3. The exception trace that is issued along with the DFHMP0002 message may also have a data2 which cannot be formatted.
Problem conclusion
DFHMPMO has been changed to stop the loop of DFHMP0002 messages after the first one has been issued. DFHMPMO has also been changed to provide a valid data2 in the exception trace (trace pointid MP 0606 ).
