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. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.11 -------- -------------------- Windows 7.0.1.11 v7.1 Platform Fix Pack 7.1.0.3 -------- -------------------- Windows 7.1.0.3 Platform v7.5 -------- -------------------- Multiplatforms 7.5.0.2 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
