Infinite loop creating server overload

I have a drupal site hosted with site ground and I recieved the following

I was monitoring the server that hosts your account jovialdesigns.com and noticed that your website was consuming a very high percentage of the server resources, thus endangering the overall performance of all the sites on the server. To keep the server at normal CPU load, we had to limit the shared server resources your account may use. This may result in occasional "Resource temporary unavailable" error messages, shown on your website.

I have conducted an investigation and it turned out that one of your scripts spawned too many processes and loops. The processes pile up and increase the server's load to critical limits. Upon further investigation, I found out that a specific script in your account loops and causes the whole problem. The script that references itself is:

http://jovialdesigns.com/files/imagecache/portfolio/

For additional information, you may see the server log below:

209.62.39.14 - - [30/Sep/2007:17:53:07 -0500] "GET /files/imagecache/portfolio/ HTTP/1.0" 200 - "-" "Drupal (+http://drupal.org/)"
209.62.39.14 - - [30/Sep/2007:17:53:07 -0500] "GET /files/imagecache/portfolio/ HTTP/1.0" 200 - "-" "Drupal (+http://drupal.org/)" 

So in order to try and resolve the problem i deleted the file location and also deleted the image cache module. I did not remove the module through the admin since my ".htaccess" was put to deny from all as a result of the overload. Rash desicoin no doubt but I was desperate, i even deleted another database, it was actually after i deleted another databass that the .htaccess was cleared but i dont know if that was coincidental

After removing the files I contacted the site support people and recieved this message:

By the time we have logged your case your script spawned more than 10 PHP loop processes + more than 10 slow mysql queries that were runnig for 30+ seconds:

As you know all mysql queries that take more than 1 second are considered as slow and they overheating the CPU and memory resources on the machine.

I need to resole the issue as quickly as possible and one of my addon domains is for a client who is about to have an art show. Her business card references the site So I REALLY need for this to be resolved. Can any one please!!!!! Help me?
