google adsense crashing my forum?

[methodx55]

i think google adsense is crashing my forum? we just signed up to be approved and i think they are checking our site...my email is getting spammed with database errors, i looked up the ip it recorded and it seems to be from google.

"Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Too many connections
/home/letstalv/public_html/includes/class_core.php on line 311"

is the main error, i keep getting them from multiple pages

edit: the emails keep coming, ive blocked the IP in my hosting control panel for now...

how can i stop/fix this?

thanks!

edit2: i just checked my board, it's up and working now...how can i prevent this from happening?
