APAR status

• Closed as program error.

Error description

• Dumps occurred during queue manager shutdown with the following
  abend codes:
  
   CSQ1,ABN= 5C6-00E70076,C=mmmmm.900.CHIN
   ,LOC=CSQXADPM.CSQXSRVR+xxxxx
  
   CSQ1,ABN= 5C6-00E70026,C=mmmmm.900.CHIN
   ,LOC=CSQXADPM.CSQXADPM+yyyyy
  
  00E70076 means CSQX_ABEND_PET_FAILURE
  00E70026 means CSQX_ABEND_ADPM_LOCK_ERROR
  
  A client channel with a non-zero SHARECNV setting was in a
  TCP/IP recv() call at the time of the STOP QMGR and the recv()
  was cancelled. A timing issue occurred relative to when adapter
  TCBs were ended as part of shutdown processing and when the
  client channel started rollback processing that needed an
  adapter TCB.

  ****************************************************************
  A client channel with a non-zero SHARECNV was in a TCP/IP recv()
  call at the time of the STOP QMGR.
  
  A timing issue occurred when adapter TCBs were ended as part of
  shutdown processing and when the client channel started rollback
  as part of channel termination that needed an adapter TCB and
  found that had terminated. This generated abend 00E70076
  (CSQX_ABEND_PET_FAILURE) when the MQBACK API need to wake up an
  adapter TCB to pass the call to the queue manager and received
  return code IEA_PE_TOKEN_BAD from IEAVRPI as result of the
  adapter TCB termination.
  
  The abend 00E70026 (CSQX_ABEND_ADPM_LOCK_ERROR) is generated as
  part of the recovery from the earlier abend.
  

Problem conclusion

• CSQXSRVR has changed to handle return code IEA_PE_TOKEN_BAD
  instead of generating abend 00E70076.
