I'm using PS3mediaserver for a few days, and it use more and more RAM.

Here you can see it use nearly 1Go, with nothing appening.
Is this normal ?
At start the program takes 70Mo, it seem it doesn't release memory after finish to transcode/stream a file ?
I'm using Ubuntu 12.04 and java 1.7.0-03.
Hardware is Dual Core 1.8GHz + 2Go RAM.
