Error description
During termination you may see an abendABM3 abend occur for the shutdown transaction, followed by a DFHSM0002 RC030E for a freemain of the DPLE subpool. The storage manager will show that the DPLE subpool is intact, and you will see that the transaction no longer has a facility address in the User TCA +x'8'. Control was in the second stage of PLTSD process. The debug profiles are being quiesced. DFHDPIN tries to send a DFHDP0300 message to the terminal, but the shutdown task nolonger owns a facility. The abendABM3 occurs. Recovery in DFHDPIN is driven, and an attempt is made to finish the debug profile clean up process, but the dplm_browse_list_token has been lost, ie., it is 0s. This causes an invald freemain when control picks up a bad address in lowcore and passes it as a QPH address in the DPLE subpool. Additional Symptom(s) Search Keyword(s) KIXREVDFW

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: DFHSM0002 A severe error (code X'030E') * * has occurred in module DFHSMGF and * * DFHDP0001 An abend (code 0C4/AKEA) has * * occurred at offset X'3420' in module * * DFHDPLM following an abend ABM3. * **************************************************************** * RECOMMENDATION: * **************************************************************** DFHDPIN can be included in the second phase Program List Table (PLT) in order to inactivate debugging profiles and issues console message MSGDFHDP0300 saying how many debugging profiles have been inactivated. However, the message may also be sent to the terminal associated with the task, which no longer exists as CICS is shutting down. As a result, abend ABM3 is issued which invokes the recovery routine in DFHDPIN. This issues a dfhdplmm function(ENDBR_DEBUG_PROFILES) with browse_list_token( browse_token ) but browse_token is zero, so an invalid FREEMAIN of a DPLE is attempted causing "DFHSM0002 A severe error (code X'030E') has occurred in module DFHSMGF" to be issued, followed by "DFHDP0001 An abend (code 0C4/AKEA) has occurred at offset X'3420' in module DFHDPLM" to be issued. The same problem can occur with MSGDFHDP0301. Additional keywords: DFHDP0301 DP0300 DP0301 CADP
Problem conclusion
Refsteps dfhdpin_issue_msg_300 and dfhdpin_issue_msg_301 in DFHDPIN have been changed to check that tczfcaaa (principal facility) is not zero and that flag tczfctrm (indicating that the principal facility is a terminal) in addition to checking that eibtrmid (terminal id) is not nulls in order to determine that MSGDFHDP0300 or MSGDFHDP0301 can safely be sent to the terminal. Also, in refstep dfhdpin_abend_handler, the dfhdplmm function(ENDBR_DEBUG_PROFILES) call will not be issued if browse_token is zero.
