Re: Gradual Increase in memory usage

From a fresh boot, memory usage averages around the 170 MB  and as time
passes it gradually increases to grab nearly all the available RAM (500MB)

This is a FAQ.


In short: it is not a bad thing. Linux sees free memory, and rather than wasting idle resources uses it as disk cache and for buffers. So while the memory is being used, it is not /in use/ as far as your interpretation of the above. It will be released to applications if/when you need it at a moment's notice.

Type the command "free" and read it carefully, especially the second line which shows the effect of subtracting the cache/buffers. I'm sure you'll find that you are actually using only what you thought.

I'll be happy not to bother you about the tagline. However, if you want to be courteous and prevent the tagline from bothering /me/, then please add two dashes and a space (-- ) at the beginning of the line above Peter Santiago. This is the official, standard signature delimiter, and will tell most intelligent mail clients to disregard this part of the text when replying. See my sig and the fedora-list footer for examples.
