CPU states:0.4% user,0.0% system,0.0% nice,...99.6% idle;

Mem 255264k av,251812 used,3452 free,0k shrd,6072k buff,209112kactv,10324k in_d,4724k in_c;

You should add some swap space, since you have none. That way, pages that are idle can be moved out to make room.

Having no swap is really a bad idea. It is almost certain that it is causing your problems. I'd create a swap partition (or a loopback file) with size of at least 256MB.

The easiest way is to create a swap file. The following instructions will create a swap file of 512MB (2x your RAM). As root:

dd if=/dev/zero of=/swap bs=1M count=512
mkswap /swap


Now, edit your /etc/fstab, and add the following line:

/swap swap swap defaults 0 0

To begin using the swap space immediately:

swapon -a

The top command will show the swap space and its usage.
