page break down due to cache

i m referring to this site:

http://www.shrishtiart.com/

I m facing a small problem in this site at these pages: ie artist details page, (choose an artist from here: http://www.shrishtiart.com/artists.php ) which uses .htacess and changes url. artist details page would be : http://www.shrishtiart.com/artist/achuthan-kudallur

So this page breaks down if you keep going through the site for normal period of time. & doesnt display results at all. its like empty RS.

Don't know what the problem is? can someone help?
i can provide ftp details

I've been clicking around for a while and it seems to be working. What exactly do you click on when it stops working? What is the url that doesn't work?

if you refreshing this page for couple of times : http://www.shrishtiart.com/artist/achuthan-kudallur

it takes long time to open in safari as well..

try visiting : http://www.shrishtiart.com/artists.php

& choose different artist one after one... then page breaks down.

I refreshed the page 100 times and didn't have any trouble. I also clicked through every artist and saw them all without issue. I'm wondering if this is an issue with your internet connection.
