Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users migrating to WebSphere MQ 7.1 when they have a channel
  indoubt may encounter this problem.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows)
  ****************************************************************
  PROBLEM SUMMARY:
  A coding error leads to the wrong code path being taken during
  channel startup if the channel status record is an indoubt
  record of an unexpected size. Encountering a status record of an
  unexpected size is not in itself a problem, but that
  unfortunately was not handled appropriately in the code.
  

Problem conclusion

• The coding mistake leading to the mishandling of an indoubt
  channel status record of an unexpected size, has been corrected.
