I’ve been having this same issue for a while now when trying to add or update posts. Some posts are ok, but certain content will seem to cause this ERR_EMPTY_RESPONSE error in Chrome. (In Firefox, the post will process for a while and then prompt to download post.php as if it isn’t executed by there server, and in IE it will give a generic “Internet Explorer cannot display the webpage” error.

I’ve created a brand new installation of WordPress 3.0.1 on the same host with a different domain, and deleted every plugin, and this error happens there also. I’ve also run Check/Repair operations on all tables via PHPMyAdmin. My host has confirmed that they don’t have any mod_security settings enabled that would prevent posts from being saved.

I’m having this same issue, but it doesnt seem to be affecting every user. Some users arent able to post certain texts, I have one post that has multiple instances of the word “from” that seems to be preventing posting. If I replace 4 out of the 5 instances of “from” it will post right away. (I narrowed it down to the second instance of “from” would be the point where the post would break, and then started replacing the instances of that word in the rest of the text. Thought it might have something to do with being a reserved SQL keyword or something…) It doesn’t appear to be related to post length, I can post super long Latin text content without any issues.

However, a coworker is able to post the same content with no problems, as is the support rep at my host. This issue affects me in both IE and Firefox. (In IE I’ll get a “cannot display the webpage” error, in Firefox the page runs for a while then I get a dialogue box asking me to save “post.php” as it were a downloadable file.) It randomly pops up for other users and their posts.

I’ve increased the PHP memory limit, the pcre.backtrack_limit and pcre.recursion_limit, and turned off mod_security in .htaccess and wp-config.php. The support rep has confirmed they’re not using mod_security or mod_security2, and there’s no reason that this should be happening as far as they can tell. I created a new installation of 3.0.1 and have no plugins enabled and still can’t post.

Anyone have any other ideas why this might be happening, and only affecting certain users?
