Apache starts lots of processes that keep alive and do not die

    Hi,

    I have some problems with my apache server: It starts lots of processes that seem to keep alive indefinitely. If I do:

    ps aux | grep apache

    I get something like below. The list increases until a huge number of processes, then apache dies with a "maximum number of clients exceeded" error.

    I'm also using a virtual host for a 301 redirect of a second domain:

    <VirtualHost *:80>
    ServerName second.com
    DocumentRoot /var/www/redirect2

    </VirtualHost>

    (In /var/www/redirect2 there is a .htaccess file doing the redirect)


    I'm lost with this. Any idea, where these flood of processes could come from?

    Thanks a lot!

    Review your error logs, see if your getting botted. Also, inspect your /tmp directory to see if there are any malicious programs running. This is why we recommend managed hosting, so you can leave the server to the pros and focus on getting traffic and your web site.

    Limit your apache process first.

    Edit :

    And add this line on that blank file :

    * Change the first number to the new process limit, then add 5 to get the second number.
