Am pretty new to server administration. So I am not able to get to the root of the problem.

I am running Apache2 with mod_php on a 1GB Rackspace Cloud Server (Ubuntu 9.10). My site goes down often, and I have to restart apache2 to get the site working.

I checked the "error.log" file. There were no signs of any error messages. I even searched for words like [error] / error / warn / [warn] . But no results.

The site goes down and even then apache is running. When the site was down, the checked the status /etc/init.d/apache2 status and it gave ** * Apache is running (pid 433). **

Any suggestions where I should look for the problem.

Thanks a lot.
