Yes, I've created that template myself. And "unfortunately" it works perfectly
fine on another machine.

I've just tried to use a precreated Sarge template (from
http://download.openvz.org/template/precreated/debian-3.1-i386-minimal.tar.gz)
but it shows the exact same behaviour.

Yes, there are lots of tty dev-files in the template. Could that be a problem?
As an experiment, I've removed them, but this did not change the behaviour at
all.

No, this shows all processes.

I'm grateful for any hints on how to debug this issue.

Thanks,
