  08/01/15 13:16:17 - Process(37991.4) User(mqm) Program(amqrmppa)
                      Host(localhost.localdomain) Installation(Installation1)
                      VRMF(8.0.0.0) QMgr(my.manager)
                      AMQ9776: Channel was blocked by userid
  
  EXPLANATION: The inbound channel 'CANAL1' was blocked from address
  '127.0.0.1' because the active values of the channel were mapped to a
  userid which should be blocked. The active values of the channel were
  'MCAUSER(mqm) CLNTUSER(mqm) ADDRESS(localhost)'. ACTION: Contact the
  systems administrator, who should examine the channel authentication
  records to ensure that the correct settings have been configured. The
  ALTER QMGR CHLAUTH switch is used to control whether channel
  authentication records are used. The command DISPLAY CHLAUTH can be
  used to query the channel authentication records.

  08/01/15 13:16:17 - Process(37991.4) User(mqm) Program(amqrmppa)
                      Host(localhost.localdomain) Installation(Installation1)
                      VRMF(8.0.0.0) QMgr(my.manager)
                      AMQ9999: Channel 'CANAL1' to host '127.0.0.1' ended abnormally.
  
  EXPLANATION: The channel program running under process ID 37991 for
  channel 'CANAL1' ended abnormally. The host name is '127.0.0.1'; in
  some cases the host name cannot be determined and so is shown as
  '????'. ACTION: Look at previous error messages for the channel
  program in the error logs to determine the cause of the failure. Note
  that this message can be excluded completely or suppressed by tuning
  the "ExcludeMessage" or "SuppressMessage" attributes under the
  "QMErrorLog" stanza in qm.ini. Further information can be found in the
  System Administration Guide.
