Help: bad memory usage and processes loaded repeatedly
Hi all, i've noticed that after few minutes of usage, my Hp's fan start twirling like hell, and after some research, i've come up with this big and silly problem...
The two screenshots here should explain you better than i can...

Is this possible? I mean, firefox replicating himself lots of times? And idem thunderbird and soundmixer? Is that a bug or what?
I really cannot explain... And my memory goes
smau@neplero /$ free -m
total used free shared buffers cached
Mem: 1941 1559 381 0 348 908
-/+ buffers/cache: 301 1639
Swap: 3812 0 3812
with firefox, pidgin, xfce. nothing else.

htop shows threads by default, not processes (i.e. you are running only one firefox). And your memory usage isn't that high (free command shows 301 MB used).

Re: Help: bad memory usage and processes loaded repeatedly
In addition, you can see in htop (left upper corner) that cpu(s) is being barely used at all. Which doesn't answer the question of why your fan "start twirling like hell".
I wonder if that's a weirdness of the bios (manufacturer setting low cpu temperature for activation of the fans), a kernel bug (forcing the fans to prematurely activate), or perhaps the cpu (or any other component) heats for some other reason.
For the first two, I wouldn't waste time researching (the lower the cpu temperature, the more it will live 
) I myself have the first issue (manufacturer set) in my acer aspire one d250 
For the last one, you might want to keep an eye on the cpu & hdd temperature. For cpu, conky (multipurpose monitoring software) used thru acpi or lm-sensors might help. Conky also has (I think) commands to check hdd temp, but hddtemp can also be used.
It might as well be due to dirt in the fan sink (if it's a laptop). I clean mine (hp laptop) up once every year (I have a dog hehe).
there may also be an option for you to control the fans (google that with your model name), but that's dangerous stuff. if temperature readings that you get in order to manipulate fan behavior is wrong (they easily might be wrong), you're screwed in the long run (cpu life decrease) or short run (stirfrying cpu).
I don't wanna behave as if I know a lot though ---these are what I would do/think if I were having your problem.
