I just disabled flash plugins (konqueror->settings->plugins) and I my memory consumption isn't atrocious. My uptime is now 3d, with 50% swap free and some RAM free as well.
In the earlier setting, with the exact same kernel and X, I didn't get more than 2d of uptime w/o running out of memory. I've filed a bug with nspluginviewer in the KDE bugzilla, but they say it's a bug in the flash plugin; so basically we can't do anything about it. -- Amit Shah http://amitshah.nav.to/
