A Transport-level Error Has Occurred When Receiving Results From The Server Error 19
An existing connection was forcibly closed by the remote host.) 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 a transport level error has occurred when receiving results from the server semaphore timeout idle for a long time, or if the 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 thi

So catch the error in your application, and reconnect. Then try the command again. share|improve this answer answered May 3 '14 at 7:06 Rob Farley 11.3k11735 add a comment| up vot
