Hi everybody! I'm using Redhat 7.3 and I have a Pentium IV processor with 1.5 Gb of RAM, but I have the trouble that when I use some application looks like the RAM doesn't clean by itself when the application stops, even when I copy a file to my hard disk the RAM doesn't clean by itself. And how do you suposse I have my RAM memory full all the time. Someone knows what can I do to fix this?
