To much memory usage

[Grinder]

How can I reduce the memory usage that is indicated on my vps control panel?
It's around 80 %

 

[m107]

Dude, provide more details! what's your usage there? are you using any control panel?

 

[l0calh0st]

If you are using Kloxo then you just need to add more DEDICATED ram.
If it's someting else then you to check apache and php settings.

80% of what? how much dedicated RAM do you have on the VPS?

 

[wman]

change your template to something simple, i think thats one of the reasons

 

[drlove]

reboot .. reboot.

 

[Grinder]

I have rebooted a few times, and still its the same.

These are the specs :

Memory: 512 MB
Burst: 1 GB
Disk Space: 50 GB
Bandwidth: 300 GB


Operating System: CentOS 5 32bit + cPanel

And here is a screenshot taken from the statistics in my vps control panel :

Chances are, your OS is caching the memory for later use and that shows up as used memory.

Looking at your load averages, your CPU utilization and the number of running/sleeping processes, I don't suppose you should worry about the memory utilization.

 

[raj11]

through ssh try this command
free -g
it will how much memory is cached

 

[w3bpr0jectz]

if you don't use email on the server disable the service, an the anti-spam service. also if you don't need nameserver running, if you use you domain provider's nameservers disable that too..

 

[Grinder]

But when it reaches around 80 % , I am experiencing slower page loads. Or has that nothing to do with each other?

And and I do not use email stuff on my server.

 

[l0calh0st]

Reinstall CentOS 5.4 32Bit, and install cPanel.

 

[drlove]

brute force attacks?

 

[DXS]

I was thinking maybe it could be DoS attack but I forgot how to check all the connections on the servers with what IP and how many connections there are. ANd then how to ban those IPs/drop the connection from a specific IP.

Wau wrote an excellent tutorial but the site he wrote it on is no longer online. :/

mysqld_safe > looks like you updated mysql but it didnt complete.

try to upgrade it in WHM and wait for it to complete

 

[m107]

also cpanel will get more than 200 mg of ram itself

 

[drlove]

plus your OS another 200 probably ... you're already on 450+ Mb of memory.
