Not for Linux. A memory leak on Linux is considered a serious bug. The
kernel will always reclaim unused memory. If you find memory is gradually
being eaten up, it means that a program (perhaps a component of KDE) is
allocating memory but never releasing it. It isn't "unused", as far as
anybody or anything can tell, so you cannot free it.
What kernel version are you running ("uname -r" will tell you). Certain
releases of the kernel *do* have memory leak bugs that have since been fixed.
2.2.11 is a recent example.

Try logging out and logging back in again. That should restart all of KDE
and restart the X server, freeing any memory they have allocated but not
released.

Run the "top" command, and then press "M" (upper-case letter M). That will
sort processes by their memory usage. What is using the most memory?
