disappearing center/content
 

So I've got a customer that believes in long pages. He broke the camel's back when he added one more image and the entire body/center goes blank.http://www.trentstudios.com/blank_center.png
Has anybody seen this before? Does anybody know what might be causing this?
I thought my client might have some funky formatting/coding on the page, so I copied the text out, saved it as plain text, copied that plain text without the formatting and pasted that into a test page.
Is there a limit to the length a page can be?
Thanks!

I notice that the right sidebar is gone. You should cause the error again and then view the page and look at the source - it may shed some light as to the last thing that was done.

I would suspect that an error occurred (have you checked the site/host logs) and my guess is that it was probably a timeout
