Single Post – No Data Receieved

Greetings all!

Have an odd problem here, wondering if anyone has advice.

I have a self hosted wordpress install. I updated to 4.0 yesterday, not sure if that’s causing the issue or not.

I have a post from October of 2013 that suddenly is giving me a “No Data Received” error in Chrome and simply won’t load in safari or firefox.

It’s odd because the site is still up. Other posts still load. I can still access the admin side of the site and I can even edit the post in question. But when it comes to previewing the post or loading the post page, it doesn’t load.

Thinking it might be a theme issue, I swapped themes, but no joy.

The post is long, so I checked some other long posts I have, those seem to be working. (I have other posts that have more words than this one, but this one might have the most paragraph breaks.) In my text editor it’s 1030 lines long.

I created a new post and copied the contents to the new post. Tried to preview it, same problem.

The post had special css classes for each paragraph, since it was a visual representation of a chat window. I tried stripping the HTML tags from the document. (Mostly paragraph tags with class declarations and some images.) Copied the 1030 lines without HTML, tried to preview the post. Same problem.

Took a hatchet to the document and started deleting sections randomly. 769 lines of text, no html markup, then it worked.

Tried a new post with just part of the original post, it worked fine. Added more until it stopped working, then started subtracting. Seems to max out at 794 lines.

Is that an expected feature? Did I just solve my own problem? Is it suppose to do that?
