Question

Strange System.Data.SqlClient.SqlException

Error at the transport level when sending a request to the server. (Provider: Shared Memory Provider, error: 0 – Since both ends of the canal there are no processes.)

I’ve got this exception on my Web Site every time after restarting my SqlServer on simple request like this :

if (System.Web.HttpContext.Current.User.IsInRole("Administrator"))

but after I do refresh the page with this codebehind error disappears.

How to handle this error and where it comes from ?

thank you.

Answer 1

If connection pooling is enabled check http://msdn.microsoft.com/en-us/library/8xx3tyca.aspx > Removing Connections.

If a connection already existing in
the pool becomes invalid (a server
restart can cause this) the first
attempt to use that results in an
exception (only then is the invalid
connection removed from the pool)

You would have to do a ClearAllPools or ClearPool (Clearing the Pool section) on the application server when you restart the SQL server.
