Connection Problems
Sorry, SMF was unable to connect to the database. This may be caused by the server being busy. Please try again later.
This one means there were a TON of people actively and the server ran out of connections and crashed. They have to bounce the database to fix it. Only way to make it go away permanently is to upgrade to an unshared server cluster = $$, I am evaluating it over the cost now.
If you see it, email webmaster@73-87chevytrucks.com and toolmaster@73-87chevytrucks.com so we can fix it asap.
