Not at all.

I suspect there is, but running it down seems nearly impossible when it 
doesn't show up for 2 weeks.

I do use inotifywait, a seperate utility to facilitate mail travel within 
the machine for one, and to issue an automatic print this command when a 
print file comes out of drivewire, but AFAIK, the rest of it is pure kde.  
I note that I found another copy of it the 2nd time I went on a killing 
rampage today, about 75 processes down from the top, killed it too, and the 
problem has not come back, but something has called up 2 copies of it since 
I nuked them all.

If that had a visible link to whatever restarts it, that would help 
considerably in tracking this down, but apparently no one knows what 
(re)starts it.

[root at coyote eagle]# lsof |grep knotify4|wc -l

How the heck can you separate the wheat from the chaff in a list that 
long..  :(

Half of that is vlc linked:
[root at coyote eagle]# lsof |grep knotify4|grep vlc|wc -l

And I haven't specifically used vlc that I know of in months, so I assume a 
news site I have visited must have called it up.

ATM, I have an eagle session on a pcb going in another window, pending info 
that I screwed the moose, so I would rather get that fixed before I reboot 

So I'll likely muddle along, keeping my rifle barrel warm if it happens 

Thanks Chuck.

Cheers, Gene
