I am quite surprised by this, but kde seems to be a real memory hog.
So what is the problem? RAM is there to be used, and that is exactly what Linux does, uses all available RAM. Would you really prefer that it start using swap? If you've got that load and your computer seems slow, then maybe there is a problem, but if performance is fine, it is just Linux using RAM the way RAM should be used.
