Too many "500 Error"

I have a fedora 12 VPS with 500 MB RAM & 1 GB swap.

I've compiled Apache 2.2.14. Also using PHP 5.3.1 via FastCGI.

I've given Apache MaxClients = 500 (ThreadLimit properly set) and PHP a
memory limit of 175M.

The problem is, some pages on my site www.itech7.com especially the
admin interface don't load properly. It takes more than 30 secs and
often results in an Error 500.

Where the problem is ? Drupal (site's app) or Apache ?

Internal 500 error's usually come from something other then apache causing the
error. Something along the lines of a Database error or an internal backend
script not functioning as it should.

No actually, all pages open. But sometimes it takes really long although
there's no traffic out there. And I checked the log to see this -

FastCGI: incomplete headers (0 bytes) received from server
"/usr/local/apache2/cgi-bin/php-cgi"

And this too-

FastCGI: comm with server "/usr/local/apache2/cgi-bin/php-cgi" aborted:
idle timeout (30 sec)

You need to check the scripts in those directories. Something within the
scripts is causing it to time out. I am guessing a database connection. I have
seen this before with other scripts.

php-cgi inside cgi-bin is just a symlink to /usr/local/bin/php-cgi.

This problem is occurring when I was recently migrated to KVM-Fedora12
from Xen-CentOS. On the previous one all was working fine, only RAM was
128 M. But one more point to note is all in the previous one were
self-compiled. Here Apache and PHP are self-compiled but MySQL from the
Fedora repos.

Any ideas ?

The first message says that Apache tried to contact PHP over FastCGI
and the script did not return an appropriate response - it didn't
return anything. Apache will then display a 500 error.

The second message says that Apache tried to contact PHP over FastCGI
and the PHP script did not return an appropriate response after the
idle timeout of 30 seconds. Again, Apache will display a 500 error.

These indicate that the problem is that your PHP scripts crash and/or
take too long to run and sometimes fail to execute within the required
time limit.

Cheers

Well, as Daniel suggested, I tweaked MySQL and configured its caches.
The things are smooth now.
Any ways how to increase FastCGI script timeout ? The default is 30 I think.
