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?
