Memory usage too high


hello all;

i have problem with memory usage. When i check it with top command , system is using 506404k from 512540k but in percent it shows only 15%. There is running only kde, firefox and apache. It seems like memory usage only increasing but never decreasing.

Mem: 512540k total, 506404k used, 6136k free, 72072k buffers
Swap: 1056312k total, 3452k used, 1052860k free, 193820k cached

Memory usage in Linux isn't what it seems. Here's an explanation, hope it helps:

it's just disk buffers and cache, the fields on the top right, it's no problem. disk caching is very low priority as far as your system is concerned, and generally speeds things up when it's being used.
it looks like it's using about 250 megs of otherwise unused ram, which is reasonable, I have a gig and it uses about 500, I also have a server with only 256 and it uses almost no memory for cache.
the memory will be availiable for applications when you need it.
