problem is, that's *the* most important page on the site.
To me this doesn't really sound like an attack. Unless you're getting
thousands of hits from the same IP it's more likely that your site has
just reached the point where its resource requirements exceed the
capacity allocated to it.
It sounds to me like you have an efficiency issue, most likely your
database connections are not being properly torn down after each page
view leading to multiple connections hanging around and gumming up your
mysql connection pool.
Are you using persistent connections? Are you on a shared (vhost) box?
If you answered yes to both questions, you have found your problem.
You'll end up with a persistent connection for every webserver thread,
most of which will actually be servicing requests for other sites *but
still using up one of your connections*.
If you are using non-persistent connections you might want to try
registering a shutdown function to explicitly tear down the db
connection, or switching to persistent connections (if you are on a
dedicated host).
