Gradual Increase in memory usage

Hello,
I am not sure if this is a problem with the kernel or due to the nature of
the programs I am running....
>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)
I was wondering if a recompilation of the kernel would help in resolving the
memory problem.....Any suggestion or advice?
