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.

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 ).
