PI69408: 0C4 IN DSR_LOCAL_PROTTERM INSIDE OF MODULE CSQ0DSRV CALLED WITH INCORRECT ADDRESS IN CBADDR PARAMETER GENERATES A CEEDUMP.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Additional Symptom(s) Search Keyword(s):
  Abend 0C4 in dsr_local_protterm calls free-to-free storage
  utilizing storage values at the incorrect address. A CEEDUMP is
  generated as a result of freeing invalid addresses. The
  incorrect address is passed once the CICS transaction ends
  without closing any subsequent handles to queues that were
  opened prior. As part of this particular processing, AMS is
  called for each of the open handles in order to free AMS
  storage. The parameter does not always pass correctly leading
  to the aforementioned issue reported.

  ****************************************************************
  When a transaction ends, CSQMCALH is called to close any handles
  to queues that are still open. For any handles associated with a
  queue that is protected by an AMS policy, CSQMCALH calls
  CSQ0CALH to perform any necessary processing in the AMS address
  space.
  An error in the parameter passing between CSQMCALH and CSQ0CALH
  causes dsr_local_protterm to be called with an invalid pointer
  to the signdata control block. When this invalid address is
  referenced or used, it leads to abend 0C4 occurring, which is
  subsequently reported by LE in a CEEDUMP.
  

Problem conclusion

• CSQMCALH is changed to pass the expected parameter to CSQ0CALH
  correctly.
