Zombie processes Firefox and Mozilla

[Markus Huber <humarfedoralists@xxxxxxxx>]

Hi,

does anyone experience zombie processes after having started firefox or 
mozilla? They are there immediatly after having started firefox or 
mozilla. I do not know since when I have them, just saw them yesterday, 
when I was tracking a bad data-harddisk - which is replaced by now.

This FC4-box is at actual patchlevel, and the versions are:
[markus@fc4 ~]$ rpm -q mozilla
mozilla-1.7.12-1.5.1
[markus@fc4 ~]$ rpm -q firefox
firefox-1.0.7-1.1.fc4

Here's an excerpt of:

[markus@fc4 ~]$ ps -ux
