Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users running on MQ 7.0, MQ 7.1 and MQ 7.5 using
  channels may face this issue.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  On a channel if we issue start channel after stop channel before
  the stop channel thread has completed its processing, the
  start channel status will not be saved. Hence when the queue
  manager is restarted the channel moves into STOPPED state rather
  than INACTIVE state as the channel status
  was saved during start channel.
  

Problem conclusion

• The code changes made will call the save channel status function
  to make sure that the start channel status has been saved when
  the start channel command is issued. This channel status will be
  remembered during the next restart of the queue manager.
