No data received or missing CSS

[kalos]

Hello everyone,

After moving to my new server, I will (seemingly at random) get errors on my blog (both the main page, and the administration backend) saying "No data received" (in the developer builds of Chromium on Linux, Firefox, Uzbl, and Midori [so it's not browser-specific]) Also, some other times the content will display, but the CSS is broken. I've tried to find a pattern as to when it happens, but it is happening frequently now, and some of my visitors have asked me what's going on with it.

Any suggestions on where to start troubleshooting?

Any suggestions on where to start troubleshooting?

A URL to said server for us to have a look at it would be good.

Please also describe your server setup...

This one is my personal blog (which is where I'm seeing the problems):

z-issue.com

Some specifics about the server are:

Linux kernel 3.3.1
Apache 2.2.22
PHP 5.3.10
MySQL 5.1.62

If you need any other information, please let me know, and I will certainly provide it.

Thank you for your help thus far.

Cheers.

Hi!

So this only happens occasionally, not always? Are you able to analyze the load of your server to see if it's maybe load-related? Did you check if you get any output in the error or syslog of your system? Maybe the PHP process or something other coredumps...

Are you running PHP as mod_php or as (f)cgi?

It does only happen from time to time, but I can't figure out why. The server load is quite low right now, and it is happening repeatedly. There is nothing mentioned in the access_log or error_log, and nothing in syslog. I am running PHP as mod_php. Here is the exact error:

***
No data received
Unable to load the web page because the server sent no data.
Here are some suggestions:
Reload this web page later.
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
***

Cheers.

Hi!

Do you have other applications running on the same webserver? If yes, do they work? If not, try to put up another application; or maybe even create a directory "static" in the s9y directory, create a ".htaccess" in it with the content "RewriteEngine Off" and another file "index.html" that simply says "Hello world". When the server itself doesn't react, try to open that static/ URL and see if that works? Then we can see if PHP/a PHP application is a culprit, or maybe even Apache is running faulty.
