A Transport Level Error Has Occurred When Receiving Results From The Server Semaphore Timeout
Server 2008 up vote 13 down vote favorite 3 I have a web application which is currently running on Windows XP operating system with SQL Server 2005 database and IIS 6.0. Now, we are trying to upgrade it to IIS 7.0 on Windows Server 2008 and SQL server 2008 database. When I run the application then it is throwing "A transport-level error has occurred when sending the request to the

This error will show if a connection is drawn from the connection pool and the connection to the server has been lost. There is no way for a connection in the pool to know that the connection has been severed. From “SQL Server Connection Pooling (ADO.NET)” http://msdn.microsoft.com/en-us/library/8xx3tyca.aspx Removing Connections The connection pooler removes a connection from the pool after it has been idle for a long time, or if the https://blogs.msdn.microsoft.com/spike/2009/04/16/a-transport-level-error-has-occurred-when-sending-the-request-to-the-server-provider-tcp-provider-error-0-an-existing-connection-was-forcibly-closed-by-the-remote-host/ pooler detects that the connection with the server has been severed. Note that a severed connection can be detected only after attempting to communicate with the server. If a connection is found that is no longer connected to the server, it is marked as invalid. Invalid connections are removed from the connection pool only when they are closed or reclaimed. If a connection exists to a server that has disappeared, this connection can be drawn from the pool even if the connection pooler has not detected the severed connection and marked it as invalid. This is the case because the overhead of checking that the connection is still valid would eliminate the benefits of having a pooler by causing another round trip to the server to occur. When this occurs, the first attempt to use the connection will detect that the connection has been severed, and an exception is thrown. Basically what you are seeing is that exception in the last sentence. A connection is taken from the connection pool, the application does not know that the physical connection is gone, an attempt to use it is done under the assumption that the physical connection is still there. And you get your exception. There are a few common reasons for this. .1 The server has been restarted, this will close the existing connections. In this case,

(provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) We have 3 web servers connecting to this SQL Server running around 100 applications (all accessing the same 8 databases on the SQL Server). Because these exceptions were not occurring on the 2000 server, we feel like it is unlikely to be an application issue (however, we are not ruling it out). Traffic on the web sites is typical, ruling out a high traffic issue. The old SQL 2000 box had 4 CPUs and 8 GB RAM, while the new one has 24 GB RAM and 16 CPUs (which is currently and during the issue underutilized). These errors occurred for a period of about 5 minutes several hours ago and have not as yet reoccurred. The sys.dm_os_ring_buffers system view does not show entries for these disconnects, and there are no corresponding event log entries on either the server or the client. Some googling has found a few similar reports, however nothing seems definitive(see links below). Has any
