Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users who cause queues to be frequently deleted and redefined
  may be affected by this issue.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  An internal counter was copied into a buffer but the buffer was
  too small to handle the value and so a memory overwrite
  occurred.
  

Problem conclusion

• The code was corrected so that the amount of data copied to the
  buffer does not exceed the buffer size.
