i am in big truble, RAM usage, please help

I have bought VPS with 512 MB guaranteed, 1GB burst, 40GB HDD, i found it is sufficient to run Website.

I want to host 2 website one with joomla and otherwith vbulletin.

i found virtualmin setting all OK.

But firstly RAM usage to 350 MB, then while adding two virtual host, RAM usage gone beyond 512 and 750 in burst.

i found it is too much , i am using centos 5.4.

What is the issue, When i was at 256 VPN from other company, the ram usage shows 180MB,

When i upgraded to 512MB, it shows 350 MB used , and increasing automatically.

in post installation process, i only activated mail lookup server, and my sql optimized for 256 MB,

really what is the issue

Kindly help

Howdy,

What is the output of these two commands:

free -m uname -a

However, the key is to disable services you don’t need.

You can review what’s running with the command “ps auxw”, and you can stop any unneeded services in Webmin -> System -> Bootup and Shutdown.

There’s also documentation here regarding optimizing your system for a low-memory server:

http://www.virtualmin.com/documentation/system/low-memory

i know that
Swap=0
it is openvz

for second command
i got this

Linux server.discusswire.com 2.6.18-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 i686 i686 i386 GNU/Linux

i found that there are 5 httpd same process running when checked running processes, each consuming 70 MB RAM

Why this,
Ram consumption increases regularl

i need mail box functionality, so shall i need postfix with devcot, or anyother low memmory substitution
can i disable awstate and weblizer, or shall i need both

i know that Swap=0 it is openvz

Sure… but what does “free -m” show? :slight_smile: That’ll help us understand what is going on with your server.

Linux server.discusswire.com 2.6.18-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 i686 i686 i386 GNU/Linux

That’s a good! We definitely want to be using 32 bit and not 64 bit on a system with only 512MB of RAM.

i need mail box functionality, so shall i need postfix with devcot, or anyother low memmory substitution can i disable awstate and weblizer, or shall i need both

Awstats and Webalizer are just for generating statistics. Although they don’t use much memory, it certainly can’t hurt to disable them if you don’t need them.

If you haven’t already, I’d also recommend reviewing the low-memory documentation that I mentioned earlier, it makes some suggestions as to what services can be stopped.

i found that there are 5 httpd same process running when checked running processes, each consuming 70 MB RAM

It’s normal for processes to use more memory the longer they run. The low-memory documentation reviews some methods of reducing how much memory Apache requires.

I have a doubt that, How ram consumption increases

and when i used 256MB RAM, virtualmin totally used 190/256 MB ONly

when i upgraded to 512MB, speed is low, and MB usage is high, Why this
