Problem summary
**************************************************************** USERS AFFECTED: WebSphere MQ v701 .NET applications running in managed mode. Platforms affected: Windows **************************************************************** PROBLEM SUMMARY: The MQ .NET application reports System.Net.Sockets.SocketException with the error message, "An established connection was aborted by the software in your host machine." This error occurs after the application thread sends a connection close request to the server following which the server closes the conversation. Meanwhile the MQ receiver thread created to service the application thread tries to send a heartbeat packet to the server following a failed receive. The socketexception is reported when the heartbeat is sent on a socket that is already closed by the server.
Problem conclusion
The MQ .NET code is modified so that the heartbeat is only sent when the receiver times out after waiting to receive data from the server. --------------------------------------------------------------- The fix is targeted for delivery in the following: v7.0 Platform Fix Pack 7.0.1.11 -------- -------------------- Windows 7.0.1.11 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 ---------------------------------------------------------------
