I would like to know how it is possible to find out what specific application is causing SQL Server to write the following message to the event log: "This SQL Server has been optimized for 8 concurrent queries. This limit has been exceeded by 22 queries and performance may be adversely affected."  Please be specific.  Thanks!

Use Profiler and set it up to track processes.  Dependgin on the timestamp, you may then be able to isolate the process that triggers that message...

Hope this helps...

SQL Server does that as informational messages to you.

There is a limit to MSDE. It can only handle 8 concurrently executing operations. After this it applies a workload governor (stalls a user connection for a few milliseconds). This then cause more concurrent queries. MSDE is ideal for small DB solutions with no more than 8 concurrent queries.

You actually have an ApplicationName column in the columns proposed by Profiler.  Just look for it closer in the right listbox that allows you to select columns in the trace property box...

You may also use the databaseid column to relate to the right application...

Hope this helps...
