Problem summary

• ****************************************************************
  USERS AFFECTED:
  All MQ users
  
  
  Platforms affected:

  ****************************************************************
  PROBLEM DESCRIPTION:
  The problem occurred because of incorrect handling of an error
  condition when reading data from queue file.
  
  The object being marked as damaged should not terminate the
  queue manager,
  the queue manager should keep running after generating a FDC.
  

Problem conclusion

• MQ code has been modified to prevent the queue manager shutting
  down due to a damaged object.
  
  The queue manager will continue running, however the damaged
  object will be reported via log messages and Failure Data
  Capture (FDC) records. This damaged object condition should be
  investigated and addressed to restore service to this object.
