well I just ssh to my tablet and I found that a lot of process are running several times in the system... So it could be that the system is not shuting down the process correctly causing the system to over load at some point... I had 4 media-server running, 3 music-player, 2 hildon-input-medthod, etc... and the list get bigger. If I am running only one instance of Music Player they shouldnt be 3 instances of music-player running....
