  ****************************************************************
  When a SVRCONN channel is processing messages on behalf of a
  client, an internal MQRC_SIGNAL_OUTSTANDING reason code may be
  incorrectly handled. When attempting to notify the client of the
  error, the callback area may contain uninitialized data which
  causes the rstConsumer code to FFST or abend S0C4.
  

Problem conclusion

• Processing has been amended to ensure the reason code is
  correctly handled.
