zombie after startup

[Sebastian Spiess]

hi all,

for quite a while now I've been having one or sometimes 2 zombie processes showing in my system monitor

I tried to kill them using the system monitor. I tried killall and PID but everything I tried did not work.
After reboot the zombie is back.

PID is always >6000 if that matters.

How can I investigate what causes this zombie and how can I kill it.
I would prefer the shot gun which worked well on zombies in some games but here in my system probably not :-)

Thanks,
Sebastian
