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.
