  ****************************************************************
  During queue manager shutdown CSQMESTP calls rsxAccessQueue to
  free the CHLAUTH cache. This attempted to access
  SYSTEM.CHLAUTH.DATA.QUEUE, however this was not defined, leading
  to an event message being generated to report this.
  As the event queue was not a local queue MQPUT1 is called to
  put the event message.
  During put processing, CSQMCHKM calls CSQMQCST to determine the
  type of the ccsid in the MQMD, prior to validating the headers
  in the message, if any - for this event message there are no
  headers and this call is not needed.
  
  CSQMQCST attempts to reference the MQ conversion tables, however
  these had already been freed earlier in shutdown processing,
  leading to the reported 0C4 occurring.
  

Problem conclusion

• Put processing is changed to skip ccsid checking for headers
  after the conversion tables have been freed, preventing the
  unnecessary call to CSQMQCST and preventing the abend
  occurring.
