high Swap 87.85 % and memory 66.3%

[cafdesigner]

I have noticed that swap of the server is being very high, around 87.96 % this is normal? how I make to reduce this?

PS: See file Attachment.

You must log through ssh, and check exact memory usage. For example you can use this command:

ps --sort=-rss -eo pid,user,rss,vsz,cmd

In ps output you must pay attention to RSS and VSZ columns. VSZ is a current size(in kiloBytes) allocated memory by process(it can be real memmory or swap). RSS is the size of not swapped memory. Determinate current swap usage by process u can just simple subtract RSS from VSZ. But you must keep in mind that it is not so currect - VSZ can be for example 100mb, RSS - 50m, but in swap will be only 32m because process allocated but used only 82m.

Overall swap usage you can see with "free" command.

And as I liberate the space in swap?

[Mr.Loge]

Yes and no. You cant reduce swap space by any command because swap is allocated by applications. For first you must find each application using much memory. This can be done by command that I post below. Next step will be killing this process, or determinating why it uses so much and reconfigure app params, or adding more memory if app require it.

p.s. In your situation it is really nothing worry about.

I am trying to create an archive for swap but this being given error, I see as I am making:

# mkdir /var/swap_area
# dd if=/dev/zero of=/var/swap_area/swap bs=1024 count=1024000
# ls -lh /var/swap_area
# mkswap /var/swap_area/swap
# swapon /var/swap_area/swap (erro on this command see:)
swapon: /var/swap_area/swap: Operation not permitted

What it is this error?

[Mr.Loge]

This is because of virtual environment. Possibly some modifications needed on host or virtuozzo dont allow this at all, anyway you can contact support, maybe they can help..

[Mr.Loge]

I'll test it on XEN, it can be done on this kind of vps.

I am finding that my swap usage is high too: 93.80 %

it's making my VPS run very slow, yet I don't think I am using high CPU programs.

The support said that is normal...

I have a 10 VPS with this question...

I have noticed swap also high, and I don´t know exactly what Rick does, but he has fixed it for me.

is the screenshot from cPanel??

I'll stay away from cPanel for a while, eat too much server resource
