Template markup on page is cut off - possibly hitting a size limit of some sorts?

Hi all

I'm experiencing a bizarre issue where some pages on my production website, ie. @@caching-controlpanel is being cut off mid-page and not rendering things such as the form submit buttons at the bottom of the page.

My suspicion is that once a view's template is more than a set amount of lines/size/bytes that it is stripping it off somehow. Is this a setting in the CMS somewhere or possibly an issue with LXML that anyone has ever run into in the past?

Thanks.

I've never noticed such a limit. If you turn Diazo off, does the problem persist?
