Hi I run Debian 6 with Apache. I'm in a vps with 1 gb RAM + 1 gb Swap and I noticed that is very easy to block all the services of the vps. It's enough to keep pressing CTRL+R for 1 minute in the home page of a fresh Joomla Installation to make freeze the whole vps for out of memory (it goes from 210 mb ram + 70 mb swap used, to 1015 mb ram + 1000 mb swap used). I dont think that's normal, how can I fix it? Should I use nginx?
