IT39743: IBM MQ process amqpcsea ended unexpectedly with insufficient diagnostics

APAR status

• Closed as program error.

Error description

• Connection to the queue manager using the IBM MQ Explorer failed
  and
  the dmpmqcfg command was unresponsive, returning "MQSC timed out
  waiting for a response from the command server to queue ''."
  
  The command server ended and the error "AMQ8506S:
  Command server MQGET failed with reason code 2033" was found
  in the queue manager error log. There were unprocessed messages
  on the SYSTEM.ADMIN.COMMAND.QUEUE queue.
  
  An FDC with probe identifier RM680010 was also seen.
  

Local fix

• Start the command server by issuing the strmqcsv command:
  
  strmqcsv QueueManagerName
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of applications that administer IBM MQ via the IBM MQ
  Command Server may be affected by this issue.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The IBM MQ Command Server process amqpcsea ended unexpectedly.
   This caused applications which rely on the Command Server, such
  as the IBM MQ Explorer or the dmpmqcfg command, to stop working.
  
  There was insufficient problem documentation to determine root
  cause.
  

Problem conclusion

• Root cause could not be established, and so extra diagnostics
  have been added to IBM MQ to assist with analysis of the problem
  should it occur again.  As well as the diagnostic change, code
  was added to attempt to recover from the issue.
  
  The code change exposes three new FDC probe identifiers:
  PC235002/PC235003/PC235004.  If FDCs are generated containing
  any of these probe identifiers then please raise a problem
  ticket with IBM Support.
