You should be able to determine what process is causing the problem by using 'ps -aux' to track the memory usage of the processes. As the day goes by, the memory used by the offending process should grow.

Variety of reasons:
Some processes share memory. Different instances of the same program will share code pages. Different programs entirely will share code pages when they use the same libraries. Multi-threaded programs will share both code and data pages. This sharing makes the sum of the memory sizes too big.
The X server will mmap your video card's memory, so its size appears considerably bigger than it really is.
You may also be looking at the wrong piece of output from 'free' or 'top', entirely. The "total" memory use reported by 'free' includes application memory use as well as disk buffers and cache.
Well, here's the problem (I should probably start a new thread for this, because it may turn out to be very eye-opening)
I had noticed that I didn't have much free memory a few days ago (I had
384M RAM installed) so I went and bought another 256 and installed it
(totalling 640M) Restarted the computer and saw that I was only using
20% of the RAM. But after a few hours, I noticed that the little gnome
bar graph was getting pretty high, so I rechecked and it was up to 85%. And a few hours later, it was over 95% and I had started using swap
space. So I thought "memory leak". I started shutting down everything
I could, rebooted a lot, and still find that no matter what I do, the
computer slowly eats up more and more RAM (10-20 megs per hour). I even
turned off every service, rebooted (less than 30 total processes
running) and still had the RAM slowly getting used up. I tried it with
kernel 2.4.20-18.9 (the newest, and the other kernels that have been
released since RH9.0 came out. As it is now, I am rebooting once or
twice a day to keep the RAM usage down, which is mildly inconvenient :(
Anyone have any ideas here?
