where's is all my memory going?


hey all,

I'm running top, and i noticed:
Mem: 513700k av, 496188k used, 17512k free

i'm assuming this is the memory on my box and how much of it is being used. if my math is correct i'm usingalmost all of my memory, and i don't know why.

here is output from top.

this is probably not a wise thing to do, but i'm trying to figure out why my memory is being used up.


i'm running RH9 on an athlon 2400 with 512MB DDR SDRAM


another thing i noticed was all there unusual processes running. such as some Bonobo-Moniker process that i wasn't able to find useful information about along with some wombat process. i don't know if it was wise, but i killed most of those processes. How unsafe is it to kill processes not started by root?

any ideas?

Hi,

Don't panic too much, do a 'cat /proc/meminfo ' from a command line. That will show you how much of your memory and swap file space is getting used.

Red Hat reserves a whole lot of the system memory, so in theory it is being used by the os, but is only reserved. The main thing is check your swap file space. Make sure that isn't getting eaten up.
