Bill.
You have had ubb for many years.
And been through many upgrades.
such as I see posts from 10/2000.
Possibly you need to do some clean up.
I think you have server logs enabled. I would look for any indication of connection issues to the database.
I would start with that.and or clean them out if they are excessive..
If you know the folder they are saved in you can delete them faster than using the ubb to delete them one at a time.
But you may get some better performance by clearing cache and optimizing tables.
This can be done from the ubb control panel.
I tried to login to your site but my email has changed since the last time I visited.
