Server Uses all Memory?

JerryMcFarts · 04-29-2006, 05:13 PM

I am confused. I upgraded my ram because my server was using pretty much all of my 128MB of ram. So I currently have 512MB

I am just running website with MySQL+PHP+APACHE nothing too extensive.

I am confused though because when I run 'top' and add up the program percentages of useage, it comes around roughly 37% but top shows up at top that its like 97%.

just wondering what I can do.

I did copy my 'top' info in here, but it looked all messy. I can do it again if people ask for it.

Linux caches memore aggressively, which is probably what you're seeing. Don't worry, cached memory is released to applications if they need it. I suggest you use the free command and look at the second line (the numbers with buffers and cached subtraced). As a general rule, so long as your swap space is not filled too much (i.e. seldom used), you're OK.

Are you talking memory% or CPU% ???.
If its memory, you're probably worrying about nothing. Lets see the output from "free -m"

I am actually talking about memory. thanks guys for the quick response.

Have a read of this. Should allay your concerns.

If it was me, I'd be much more concerned about the occupancy of that root of yours.
94% of 37 Gig - holy mackeral !!!!

lol, yea my server, i screwed myself up and i had to reload everything, so i backed up everything using tar, so i have some duplicate files i can delete. which i just need to have some time to get around to it.

thanks for the link.
