Problem summary

• ****************************************************************
  USERS AFFECTED:
  This may affect users who have defined a subscription to the
  $SYS/MQ/INFO/QMGR/queue_manager_name/Monitor class of
  meta-topics
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  At queue manager startup a shared memory resource is created by
  one thread and accessed by another.   The shared memory resource
  may not have been created when the accessing thread tried to use
  it and so an FDC record was created.
  

Problem conclusion

• The code has been modified so that the thread which is trying to
  access the shared memory resource will ignore the fact that the
  resource does not exist rather than report an error.
