IT12477: IBM MQ 8.0 CHANNEL IN STUCK INITIALIZING STATE AND FDC PRODUCED FROM AMQRMPPA PROCESS WITH PROBEID XC130003.

APAR status

• Closed as program error.

Error description

• Channel will not connect and display shows channel in
  STATUS(INITIALIZING).
  amqrmppa process issues initial FDC with a Probeid XC130003.
  Subsequent FDC's issued with the following pattern:
  
  amqrmppa  42240  33 XC130003 xehExceptionHandler STOP
  amqrmppa  42240  33 RM042101 rrxReportError      STOP
  amqzxma0  80262   1 ZX005022 zxcProcessChildren
  lrcW_S_FAST_PATH_APP_DEAD
  
  FDC pattern repeats as channel attempts to start.
  

Local fix

• Disable the message suppression function to prevent this
  scenario.
  
  Unset the following environment variables to disable the message
  suppression function:
  
  MQ_CHANNEL_SUPPRESS_MSGS
  MQ_CHANNEL_SUPPRESS_INTERVAL
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using SVRCONN channels and queue managers configured to
  suppress error messages
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A coding error meant that it was possible for the channel
  process to fail to initialize an internal channel attribute used
  when suppressing messages to fail to initialize. This in turn
  caused a memory exception when attempting to suppress error
  messages.
  

Problem conclusion

• The MQ queue manager channel code has been updated to correctly
  perform the initialization of this internal attribute.
