Why even simple pages like phpinfo is cut off on specific server?

Question

On one of my clients production servers (Linux, Apache, PHP5) simple page output is returned partially and only to Google Chrome.

For example, I have set up simple phpinfo page, like <?php phpinfo(); ?>

When I call that page like http://192.168.1.1/phpinfo.php on IE or FireFox it nicely returns whole phpinfo page. But when I open this page in newest Google Chrome (v.30) it gets cut off at some point. Sometimes it's after 1-2 "screens", when I hit F5, it reloads longer chunk - 5-6 "screens" long, but still not all. If I hit F5 again, it returns 2-3 "screens" long page and so on.

Any ideas what's the problem here? Opening, closing Google Chrome don't help. Cleaning temporary files don't help. I have no more ideas :(

EDIT: Added screenshots to demonstrate this issue more clearly.

1) Opening phpinfo page in Google Chrome: first image you can instantly see that page is much to short for phpinfo

2) scrolling to the bottom and you can see that it's only part of phpinfo page second image

3) now pressing F5 to reload page 4) as you can see - page is much longer now enter image description here

5) but still not full php info page enter image description here

6) Also I see error in Google Chromes console like this enter image description here

7) and here is all request headers (sent / received) enter image description here

EDIT 2: In FireFox page almost always loads as full page, but not always. Sometimes it also gets cut off. Only difference with Google Chrome is that in FireFox page always loads for at least 90%. In Chrome I sometimes even get page with only 5% of content in it.

@romaninsh a lot of screenshots added and also steps to reproduce — DarkSide, Nov 05 '13 at 15:15
Please also see my edit nr.2. Firefox have same behaviour, but it's more "stable" :) — DarkSide, Nov 05 '13 at 15:27
when you say it still only loads 90% in firefox, I think its pretty clear that your problem here isn't with Chrome loading less than 90%, but that no matter what browser you're using you don't get 100%......... — Rooster, Nov 05 '13 at 15:30

Step 1: What does the log say? Can you turn up logging in apache, and tail the log for segfaults or other issues?
What happens with a long static html page (avoiding the PHP engine). php -i > ./test.txt, then grab that page with the browser.
If you view source is the entire page returned (maybe a custom style sheet is causign issues, or a proxy), or is it being truncated as well.
