While editing value in a high transaction QES database users receive the following error message:


Unexpected Save Exception Save Failed Execution timeout expired the timeout period elapsed prior to completion of the operation or the server is not responding


This is because two users happened to edit the same record or table at exactly the same time while using QES.   Because of that SQL server is letting the user know that it could not save their value they wanted to enter in.


To fix this issue you can add a Connection Timeout value to let SQL server try the data save over a few seconds.
