After 40 minutes the computer is very slow. I have opened only Firefox and Terminal.
This Polkitd is taking 300MB of memory...and highest CPU.

The commands:

#here the memory cache is not freed!
I've killed polkitd and the memory was freed:
ps -e | grep polkitd

But the memory is slow filling up although I don't open other
applications!

Now I will close firefox to see if the memory is freed!

The system is very slow. The memory is not freed after closing a program. (-pae)
