Linux, an Operating System with Memory Leaks?
I've been using Linux for my online web server (run level 3) for several years, and I have noticed that the Operating System by itself consumes all the RAM memory of the server, no matter how much it has!
The moment I reboot the server the free memory is quite high, but it starts immediately to decrease little by little, even if no applications are running! The consecuence is that in a matter of hours or days, 99% of the 500Mb or 1Gb of RAM is used up!
I have tried to fix this by trying different distros, and by updating packages, but with no success. One of the servers had RedHat 9 with 1Gb, the other two had Centos (4.1 and 4.3) with 500Mb
So it seems to be a general issue with Linux, and I expect you all have noticed it (or can confirm it now by running 'free' from time to time after rebooting).
Is there any way to fix this?
I would appreciate very much any hints or help.
