Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  MQ users with queue managers using linear logging, who record
  media images of queues which contain messages with differing
  priority values.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A defect in MQ media image logic could cause the queue manager
  to record a corrupt
  media image for the queue. When the queue was recovered, it was
  restored from the bad media image and so was still damaged after
  recovery.
  

Problem conclusion

• The IBM MQ media image logic has been corrected.
