Error description

  • When MQe client tries to establish a new connection to the
    server, after a socket timeout issue, a memory access violation
    occurs and the program abnormally terminates. This occurs while
    sending and receiving messages to a remote queue manager. The
    memory access violation abnormally terminates the client
    program. The error occurs only on the usage of C Native code
    base of MQe.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQe 2.0.2.14 and below
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The problem was caused due to incorrect handling of the socket
    timeout error in the MQe client C native code base. The mutex
    used to ensure thread safety, was not handled correctly and led
    to this memory access violation.
    

Problem conclusion

  • The fix ensures that the socket timeout does not cause a memory
    access violation. In case of a socket timeout the MQe will
    handle the condition internally and return an appropriate error
    code based on the calling function.
    

Temporary fix
