Not closing will use up this port range unnecessarily.Ĭheck the efficiency of your stored procedures anyway as they might be taking longer than they need too. You should double check your database and recordset connection are being closed after use. Will need to reboot for changes to take effect. Make sure you back up registry or snapshot server before making the changes. Search Microsoft Knowledge base for "MaxUserPort" and "TcpTimedWaitDelay" and make necessary registry changes. You can monitor these first to see if going over max limit. You might want to consider increasing this if the sites on your server are particularly busy or your application is making a lot of database calls. Look at the usage of the ephemeral ports by the IIS server. Our issue was solved by increasing number of ephemeral ports available. We recently had similar issues moving to IIS 6 from IIS 5 connecting to SQL 2000. Sounds like the database connection is getting dropped or timing out. This problem was resolved in conjunction with another similar error I posted, found here: Why is my SqlCommand returning a string when it should be an int? While we still don't know the underlying reason that a connection pool would get so mixed up, we were able to cease all errors of this type. Once we refactored these methods to immediately close the connection with a C# "using" block (freeing up that pool for the next request), we received no more errors. ![]() Instead, through some sloppy programming originating from a misunderstanding of LINQ connections, the DataContext objects were disposed (and connections closed) only at the end of a request rather than immediately. Through trial and error, we eventually tracked down a handful of SqlCommand or LINQ queries whose SqlConnection wasn't closed immediately after use. Under heavy load, including some crawlers, things got crazy and these errors poured in nonstop. After a few months of ignoring this issue, it started to reach a critical mass as traffic gradually increased.
