I've noticed that after I dont restart my computer for a few days the ram usage will be a lot higher then it was an hour after I rebooted. For example, lets say after a reboot I only use 500mb out of my 2gb, I open a few programs/watch a few tv shows/listen to some music et cetera and when I'm done with them I close them. At this point I'll probably have about 800mb used, after this same cycle a day or two later I'll barely have any programs running yet 1.8gb of ram is used!
At first I thought it was due to me running compiz-fusion and about 12 superkaramba themes, but then I noticed after a reboot even with all these open it only took up about 500mb. My computer has been "up" for 1 day 18 hours and 41 minutes and 1,934mb out of 2,026mb of ram is in use even though the only programs I have open are firefox, konqueror, KDE SysGuard, amarok, superkaramba, compiz and the normal background kde processes.
Ive noticed that the ram usage of mintupdate has increased tri-fold in the past 1.5 days its usually around 50-60mb when now its at 155mb even though i never touch it. one of the superkaramba themes (logwatch) is at 142mb when it should be around 30mb (all the others are at 17mb but theyre small sensors), firefox is taking up 109mb (not really out of the ordinary, i have 4 tabs open), xorg is at 101mb and amarok is at 55mb.
is there anyway i can tell these processes to free up memory? there is no reason for something that reads the info from 4 logfiles to take up 142mb of ram or for mintupdate to increase its usage trifold.
