Is anyone else having trouble posting large topics/ replies?

go ahead an try it, copy about 100 lines of text from a website and try clicking "preview post"

For me it just goes to a blank page, it won't actually show the post. and if i try to post it does the same thing, and no response is created.

I'm just wondering if anyone else is having the same problem.... this is a new problem, because everything was working fine yesterday.

I've tried clearing my browser, trying a different browser, logging out and back in, restarting the computer... nothing works.

The new server had a smaller MySQL limit. I increased it. Can you try again and let me know?

[Skippy]

Nope try bumping it up to like 1000 and lets see.

I get a 500 after 0.5Mb POST request to preview

HTTP/1.1 500 Internal Server Error 
Date: Mon, 17 Jan 2011 13:54:49 GMT 
Server: Apache 
X-Powered-By: PHP/5.2.16 
Vary: User-Agent,Accept-Encoding 
Content-Encoding: gzip 
Content-Length: 20 
Connection: close 
Content-Type: text/html

Appears to be memory exhaustion. May be in Apache error logs.

0.5Mb would not be a problem.

The post I am trying to make is less than 5Kb.. (less than 5,000 bytes/chars)

I even tried just posting 1,000 bytes of it. I still get an error. It seems anything more than like half a kilobyte directs me to an empty (literally, nothing in the HTML source code) page. So I can only make posts up to 500 letters long(half a Kb)? which turns out to be roughly 100 words or 5-10 lines? that's not enough.

Just figured out that this is an issue with mod_security and vBulletin, not a MySQL or memory issue. (This server has 4GB). I think it's fixed now. Can you check?

I had an issue with a 3 line post.

[Skippy]

It worked, thank you :)

Problem solved

Do you still? Can you let me know where the problem is?

I would imagine mod_security (which with some rule sets runs regular expressions on EVERY bit of each POST large request) goes well with vBulletin, Apache has signs if it a fatal error at per process memory, or module, I have no access to the logs so it was just a guess.

Either way, a 0.24Mb POST to the preview page successfully runs up until the 30 second execution limit, so at least that problem is saved. I had tested in two contexts. So good job.

[Roger]

Yes, mod_security was definitely the culprit, since it broke on the "Live" page as well. The log does show that the PCRE limit was exceeded for those requests. I might've been able to comment out some of the rules, but that would be too much hacking for my liking. So instead, I just disabled mod_security for some key vBulletin pages.

Unless I stumble across the post I was trying to reply to again, it'll be hard to try to duplicate. I haven't noticed anything in the last couple days.
