XF 1.1 Rebuilding Error

Whenever I try to rebuild from /install, it runs fine for about 5 minutes. When it starts rebuilding the templates, it suddenly stops and shows the following message:

"The requested page could not be found."

I have tried rebuilding over 10 times, and they have all failed. I also checked server error logs, it has no errors relating to this problem.

1) Remove any excess styles or languages that you aren't using. That will speed up the rebuild.

2) You can try adding this line to your library/config.php file to increase the timeout (default is 10):

$config['rebuildMaxExecution'] = 10;
I have removed a couple of styles which I almost never used. I also changed the value for that config option to 20. Then I ran the rebuild process again. Sadly, same thing still happens.

While it's rebuilding the templates, it randomly stops and shows the following message:

An error occurred or the request was stopped.
After that, it shows the following error:

The requested page could not be found.
I use memcached and APC caching, if that helps.

Well the "not found" error may indicate a server issue. It sounds like the server is interfering with the request if it says the resource was not found. It could be due to a misconfigured Apache module like mod_security. You would have to ask your host about this. Ideally there will be logs on the server that will reveal the nature of the problem and point to the cause. Or more generally I would ask your host to disable mod_security and any other restrictive Apache modules to see if that fixes it.
It's actually a VPS, so I can disable it my self. I will go ahead and try that right now. Also, where would I check for the logs?
Before I continued to disable mod_security, I looked at the logs once more.

Edit: I have fixed this issue by switching my PHP handler from mod_fcgid to cgi.
