High RAM usage when idle

Yes I searched but did not find an answer.

According to Conky RAM is constantly using over 150M without any running applications. Main consumers seems to be (with current amount)

browserd (19,4M)
modest(18,4M)
rtcom-messaging (16,2M)
osso-addressbook (14,7M)

Some processes pops up like camera-ui. CPU usage varies but seems to be quite normal.

I know these processes are nothing special, but I believe this amount of RAM usage is. Last 10 mins it has been around 180M. Uptime 45 mins. I do monitor running processes daily and this is new.

I have rebooted several times without success. Last changes I made we're modifying desktop with Theme Customizer and added a bookmark to the desktop. Yesterday I updated CSSU via FAM. I uninstalled TC and removed the bookmark. I did killall browserd but it changed nothing.

Of course reflashing is an option, but I would naturally like to try something else before that.

It's perfectly normal. N900 needs more RAM than it has simply to boot up. I wouldn't worry about it.

Nothing wrong with that - That's the standard behavior of any Linux system: Linux automatically uses any free RAM that it has for caching purposes. It will be reallocated once a program actually needs it.

Thanks for your reply, I know these processes are nothing special and it is doing it all the time. It's just that I have not noticed this high consumption an hour after boot.

cheers

Re: High RAM usage when idle

Linux will always use as much ram as it can. Thats why it tends to be much faster than windows as windows prefers "swap". Plus Linux manages ram a whole lot better.

Have to disagree somewhat. One of the biggest grievances for me as mousesuperhero (I hate using keyboard :|) is that I find most windows managers (mostly kde/gnome/compiz) with intel or nvidia GPUs tiny winy slower on screen rendering compared to Windows (flickering, redrawing, tearing etc.). Then again mostly on my system linux beats hell out of win on networking and disk IO. For some reason I still manage to make my win system almost complete halt with just simple dvd-drive recognization or network drive that is unreachable.

But on graphic side and responsiveness (how long it takes to menu popup when you point/click it with mouse, small differences make using menus to me unbearable) I hope that Wayland manages to help on some speed issues which might seem to be irrelevant to x-term warriors :)

.edit
And for some reason I think that making GUI fast as possible and then faster could be the most important thing to do when you start marketing stuff to Average Users. We are not talking about seconds but milliseconds that matter. Btw. From wiki citation:
