Local fix

Problem summary

• When using a Bridge Agent there was a race condition that could
  cause a failure to delete the source file when the source
  disposition had been set to 'delete'. The following exception
  was seen in the output0.log for the bridge agent:
  BFGBR0062E: An internal error has occurred. Request for session
  container for transfer Id TRANSFER_ID/Sender occurred when it is
  not present.
  
  USERS AFFECTED:
  All users of the Protocol Bridge
  
  PLATFORMS AFFECTED:
  All
  

Problem conclusion

• Due to a race condition between the transfer thread and the
  thread that will drive the deletion of the source file,
  incorrect logic could cause the bridge session that contained
  the connection to the external file server to be closed. This
  meant the file could not be deleted after the transfer had
  completed. The APAR solves the issue by correcting the logic so
  that the bridge session is not closed if it is still required to
  drive the source disposition of delete.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 7.0.4.2.
