Errr … you WANT the OS to cache stuff in ram otherwise you server
will slow to a crawl as every disk access is uncached.

Yes, you are correct Dave. I thought perhaps Elliot knew something about
Redhat 4 that I wasn’t aware of. All my packages are up to date, and I
haven’t seen any existing bugs that might cause a memory leak. I’ve
recorded the RAM usage of all running processes after the machine was
rebooted, and I’ll record the RAM usage again after the RAM fills up to
see which process is in fact the culprit. I’ll post the results in a day
or so, or as soon as the RAM is full.
Please excuse my bad english…
I use nginx version: nginx/0.5.35 built by gcc 4.1.1 (Gentoo 4.1.1-r3).
Load
average: 0.08, 0.06, 0.01. This server provide 10-12M/s images content.
And
my config is:
user nginx nginx;

use epoll;

Thank you Yordan, I will try some of the settings from your config file.
btw i compile my nginx with “–without-http_charset_module
–without-http_ssi_module --without-http_auth_basic_module
–without-http_autoindex_module --without-http_geo_module
–without-http_map_module --without-http_limit_zone_module
–without-http_empty_gif_module --without-http_browser_module
–without-http_upstream_ip_hash_module”

After a lot of analysis I have found that Nginx was not the source of
the memory leak.
After setting up cache-control this did help a lot with bandwidth. Is
there a way to setup cache control on the same server to deal with
caching images one way, and .html, .css, and .js files another way in
the nginx.conf?

I suspect you has no memory leak at all. It’s very typical for Unix
systems
to keep free memory as small as possible (here is 11M only from 2G) :
last pid: 79350; load averages: 0.39, 0.46, 0.41 up 33+17:16:00

CPU states: 25.8% user, 0.0% nice, 11.4% system, 9.8% interrupt, 53.0%
idle
Mem: 103M Active, 1430M Inact, 378M Wired, 83M Cache, 63M Buf, 11M Free
Swap: 2096M Total, 4872K Used, 2091M Free
