Do you run it for more than a single day at a time?
I have huge memory leak problems. Admittedly, my 2GB RAM is not a real lot today, but after 10 days
of uptime there is 1.4GB of swap in use and increasing. Processes like kded4 and kdeinit4 are huge.
More memory is on the way, but at this rate it is not going to help much.
With a previous (KDE3) install I could keep the system running (and logged in) for 6-12 months without
I read that others using KDE4 have had this problem for several years, and nothing has been done.
