Ado Error 3617
Escalation Services team. How It Works: Error 18056 - The client was unable to reuse a session - Part 2 ★★★★★★★★★★★★★★★ psssqlDecember 29, 20101 0 0 0 I have had several questions on my blog post: http://blogs.msdn.com/b/psssql/archive/2010/08/03/how-it-works-error-18056-the-client-was-unable-to-reuse-a-session-with-spid-which-had-been-reset-for-connection-pooling.aspx related to SQL Server 2008's honoring of an query cancel (attention) during the processing of the reset connection. This blog will augment my prior post. Facts You will not see the sp_reset_connection on the wire when tracing the network packets. It is only a bit set in the TDS header and not RPC text in the packet. sp_reset_connection is an internal operation and generates RPC events to show its activity. Newer builds of SQL Server added logical disconnect and connect events. http://blogs.msdn.com/b/psssql/archive/2007/03/29/sql-server-2005-sp2-trace-event-change-connection-based-events.aspx An attention from the client (specific cancel or query timeout) records the time it arrives (out-of-band) but the attention event is not produced until the query has ceased execution, honored the attention. This makes the start time of the attention the received time, the end time the complete honor time and the duration how long it took to interrupt the execution, handle rollback operations if necessary and return control of the session to the client. The questions normally center around the Error 18056, State 29 and how one can encounter it. I have outlined the high level flow in the diagram below for producing the error. The application will reuse a connection from the pool. When this occurs the client driver will set the reset bit in the TDS header when the next command is executed. In the diagram I used an ODBC example of SQLExecDirect. The command is received at the SQL Server, assigned to a worker and begins processing. If the reset bit is located the sp_reset_connection logic is invoked. When tracing the RPC:Starting and logical Disconnect events are produced. The login is redone; checking permissions, making sure password has not expired, database still exists and is online, user has permission in the database and other validations take place. Client explicitly cancels (SQLCancel) or query timeout is detected by client drivers

A system attention occurs when the client cancels a running request. This can happen if the command times out for example. This error is normally not sent to the client however.There is a special case where this can occur that you may be hitting. When you re-use a pooled connection, the first outbound request sends a special bit flag on t
