Memory usage floating between 90% and 100%

[jbrouhard]

Is there any particular reason, that on a freshly installed system that my ispCP Omega setup is eating almost all my memory? I have roughly 512MB of RAM in the machine.. and only 12K is free.

Running top, i see mysql server is running 3.5% of that memory, and I can't figure out where the rest is going.

ANyone got any clues or ideas ?

What about your swap? Is your system already using the swap?

If not, thats normal. Unix systems are using the free memory for the systems itself. If memory is needed. The unused / optional stuff in the memory iss freed. Only if your system is using the swap, then you have not enough memory.

This is NOT a ispCP problem.
We only use Services that comes with your Distri.

But back to your Question, it runs here with 256MB and only 203MB are really used.

You can also you "htop" (need to be installed by apt-get install htop)
it is even nicer than top a have more info.

linux != windows

free ram is bad here
Each bit of ram should be used to gain optimal performance - and thats what linux is doing. Only if the System is constantly swapping and beginning to react slowly you'll have to change something ... or worry about too much services - too much load or so.

Personally, a system shouldn't be using 90% of ram.

I know it's not a ispCP problem.. I see this on PLESK as well. I never could figure out why, so was just wondering if anyone got ideas as to why.. I odn't see this on any of my other linux servers, if at all. not even on my dev box.

Anyways, thanks alot. I'm liking the new ispCP Omega version, and will be migrating my PLESK users to it in the next few days (PLESK royally screwed me over...)

mh Windows is doing the same thing (use the whole ram for caching) it just doesn't show the ram than as being used...
And maybe its not as agressive in caching as linux is - but the concept is the same.

As i said - who buys to see that its not being used....
Just use top and see whats used and whats cached...
