Error logging alarm event to the database

I am getting the following error from time to time:
[attachment=1]AlarmLoggingError.jpg[/attachment]
The StoreAndForward feature is configured as follows:

I’m using Ignition 7.8.4, MS SQL Server 2014.
Any suggestion?

Go to the Status section and check the ‘Database connections’ and ‘Store and Forward’ pages. Make sure that your database is able to keep up with Ignition - if you notice all of your assigned DB connections in use, or that records hit store and forward and aren’t able to get immediately cleared out - that’s why you get those messages.

You may need to increase the number of DB connections allocated to Ignition, or tone down the number of DB requests, if you notice any abnormalities.

Hallo PGriffith,
thank you for your reply. What do you mean by

You may need to increase the number of DB connections allocated to Ignition

At MS SQL Server level there is only one option regarding connections:

As you can see, more then that is not possible.
Please consider that I have many other applications out there, where MS SQL Server is the backend database and a .NET application is the frontend, where I execute 20 SQL commands/second against the database and they don’t have any such problem.

Any other suggestion?
Regards
