We are intermittently receiving the following error. This is very infrequent but the magnitude is enough to trigger alerts from our error monitoring system. They last about 30 seconds and dissipate. They seem to happen without any other major changes in traffic or resource consumption on the SQL Server or the Application Server that is attempting to instantiate the connection. They do occasionally, but not always, get thrown in conjunctions with spid reuse errors on the SQL Server.
We are using ADO.NET to create the connections.

Any help is appreciated.
