I have just set up a new VPS server with Debian 6 and ISPConfig 3.0.4.5. I followed this guide: http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-courier-ispconfig-3-p3 The problem is that the server is consuming all of my RAM. It doesn´t matter if I give the server more RAM it just keeping eating it. The strange thing is that I have no working site on the server yet but it still eats up my RAM. The only thing I have installed are what the guide says I should install. My VPS host says that it maybe is apache that is eating the RAM, some kind of loop? Is there something I can do to find out what is causing this?
At first 1,5 GB. It worked fine for a few hours but after that it had eaten it all up. So then I changed it up to 2 GB, and then to 3 GB and then to 4 GB. It consumed that to.
Maybe I should mention that if I restar apache then all RAM memory is free again but after a few hours it fills up again.
Do you have munin installed to find out what is causing this? Did you take a look at Code: top ? Have you tried to optimize Apache (see http://www.howtoforge.com/configuring_apache_for_maximum_performance )? Do you use a PHP opcode cacher like Xcache or APC?
No I don´t have munin, how do I install and use that? I don´t use xcaxhe or apc, I think. No I haven´t done anything with my apache, just installed it. It worked fine och another server that runs EHCP sp I thought it would work fine with ISPConfig also.
if I would guess I think my problem is similar to this: http://www.webhostingtalk.com/showthread.php?t=971810 But I don´t really know where to start in order to solve it?
I have put a test site on my server with ISPConfig now but the site is really unstable: http://www.ffatest.se/ Most of the time it won´t load and from time to time the server CPU goes up to 200% load. I managed to get the RAM under control by changing the FastCGI Children and FastCGI max request to 4 and 200. But something must be very wrong in the server configuration since the site won´t load most of the time and gives me internal server error sometimes. It seems only to be unstable when i am using fcgi. Instead of mod_php.
You can installl Xcache as follows: Code: apt-get install php5-xcache /etc/init.d/apache2 restart munin can be installed as follows: http://www.howtoforge.com/server-monitoring-with-munin-and-monit-on-debian-squeeze
