i've been trying to determine where the problem's coming from, not wanting to
look at the kernel 'cause well... i don't know how to fix that. but i can't
avoid it. my router is a k6-II running gentoo-sources, iptables, sshd and
that's it. and here's the output of free:
# free
total used free shared buffers cached
Mem: 25992 25492 500 0 176 3396
-/+ buffers/cache: 21920 4072
Swap: 136544 1684 134860
now i understand that linux likes to use all of my ram, but caches most of it,
so the "free" column should be rather low, but 500bytes? and where's all the
rest of my ram gone? the box doesn't do anything other than route packets!
my fileserver/webserver is showing the same symptoms, though it's running
apache, mysql, samba, nfs, sendmail, rsyncd, and sshd. and i can't afford to
shut much off, so i can't be sure if it's the kernel in it's case, but here's
the output of free on that box:
free
total used free shared buffers cached
Mem: 256580 252904 3676 0 25148 55208
-/+ buffers/cache: 172548 84032
Swap: 530136 3720 526416
my fileserver has considerably more ram, but nearly all of it is used. the
box doesn't even run x, so why all the usage? is this a leak? can i have
some suggestions as to how to track it down and fix it? are there common
pitfalls a guy can run into when configuring a kernel?
any help would be greatly appreciated.
