Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ .Net interfaces.
    
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    MQ .Net classes initialised trace such that trace status changes
    such as trace start, stop could be missed.
    In some cases, trace entry was skipped but not trace exit
    resulting in a crash when trace was turned off.
    

Problem conclusion

  • The .Net classes were modified to track trace status
    dynamically.
