Hi,

We are using SmartConnector 2.4.17. After restarting our server we got the following error:

2020-10-28 08:27:24.5174,Error,Service,<no principal>,Class not registered

An exception occurred while initializing the database. See the InnerException for details.
An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy.
The underlying provider failed on Open.
An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy.
The client was unable to establish a connection because of an error during connection initialization process before login. Possible causes include the following: the client tried to connect to an unsupported version of SQL Server; the server was too busy to accept new connections; or there was a resource limitation (insufficient memory or maximum allowed connections) on the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

After starting the SmartConnector service manually, it started with no problems.

Any idea?

Thank you.

Hi Michael,

From the errors, it looks like there was an issue connecting to the Smart Connector database.

Was this a one time thing, or do you see this occurring often?

Best Regards,

Hi Jeff,

I don't recall if it happened before. It doesn't happen often.

Thanks.

Mike
