Version: (using KDE KDE 3.5.5) Installed from: Ubuntu Packages OS: Linux As I was trying to figure out why my computer was being so slow, I noticed I had three instances of nspluginviewer running, as well as three instances of mplayer - even though I closed all Konqueror windows. Here's the output of "ps x": PID TTY STAT TIME COMMAND 19547 pts/8 Ss+ 0:00 /usr/bin/kdesu --nonewdcop /usr/bin/kcmshell kde-clock.desktop --lang en_US 3359 tty1 S+ 0:00 -bash 3394 ?

But, you can see "konqueror [kdeinit] http://www.youtube.com/watch?v=CdK2ecxy9kU" running, among other things. I tried to make it visible using dcop - but dcop would just freeze. I can understand that Konqueror sometimes freezes... But, shouldn't there be a way to detect that something went wrong? It's using up lots of memory, and a bit of CPU, too. But, even if I run "ps", it's hard to notice anything if I have multiple Konquerors running.
Can you find steps that would allow someone else to reproduce the problem?
Do you have konqueror preload activated?
I'm closing this because of no answer from the reporter. Probably he activated the preload x istances feature.
