Problem summary

  • ****************************************************************
    USERS AFFECTED:
    WebSphere MQ managed .NET applications.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    WebSphere MQ managed .NET application intermittently reports
    MQRC_CONNECTION_BROKEN error during disconnect with the
    following exception.
    
    System.Net.Sockets.SocketException
    Message: An invalid argument was supplied
    StackTrace:
    at System.Net.Sockets.Socket.Shutdown(SocketShutdown how)
    at IBM.WMQ.MQTCPConnection.CloseSocket()
    at IBM.WMQ.MQFAPConnection.Close(MQTSH tshc)
    at IBM.WMQ.MQFAPConnection.Disconnect()
    at IBM.WMQ.MQFAP.Disconnect(Int32 hConn, Int32& compCode,
    Int32& reason)
    at IBM.WMQ.Nmqi.ManagedNmqiMQ.MQDISC(Phconn phconn, Int32&
    pCompCode, Int32& pReason)
    
    This was because the System.Net.Sockets.Socket.Shutdown invoked
    while closing the socket was intermittently reporting
    SocketException.
    

Problem conclusion

  • System.Net.Sockets.Socket.Shutdown invoked while closing the
    socket intermittently reports SocketException. The WebSphere MQ
    .NET code is modified to ignore this exception and proceed
    towards closing the socket.
