Error description

  • A Message Service Client for .NET v2.0.0 application using
    WebSphere MQ v7 client throws the following exception, while

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere MQ running multi-threaded XMS .NET
    Client ( Managed mode ) applications where each thread sends a
    message to a different queue manager (with different queue
    names)
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    Access to shared objects containing the connection names were
    not synchronized correctly between different threads. As a
    result, the connection information was being changed by
    different threads causing a 2085 exception.
    

Problem conclusion

  • WebSphere MQ was modified such that the connection information
    does not get shared between multiple threads, thus eliminating
    the cause for 2085 error.
