Security: site hammered, need help (2 posts)

    My hosting company (Lunarpages) has shut down my site twice now (once a few months ago, the second time this weekend) for excessive resource usage. I'm running the latest WP, and have a few different security plug-ins installed, but clearly they're not doing enough.

    LunarPages is zero help at troubleshooting this further, and I'm about to jump ship from them. But I'm wondering if anyone has any useful pointers to help me out of the woods.

    They told me to look at my Resource Usage Stats and then "take appropriate action to reduce that usage." (I have no idea what that would entail.) But I did find my Resource Usage Stats and have copied and pasted them below. I guess this means my index.php and wp-login.php pages are getting hammered?

    (Oct 5 and 6 are overload days; Oct 4 is a typical no-problem day.)

    Hi,

    Do you have access to the web server logs? Such logs should help you identify what is really happening i.e. from where the connections are coming and what they are trying to do.
