I have following issue with Knot: when I try to stop it by command /etc/init.d/knot stop then the daemon is still running. If i run command knotc stop then it's stopped but immediately run again. If I kill it by command kill, it's the same...

As I found the /etc/init.d/knot is not working at all and Knot is probably run during boot by /etc/init/knot.conf and I'm not able to control it. The "unkillable" proccess is named /usr/sbin/knotd -c /etc/knot/knot.conf

My environment: Debian 7 AMD64, OpenVZ container, kernel 2.6.32-openvz-042stab092.2-amd64, Knot 1.5.0-1

I tried to install Knot on another older machine where is Debian 7 too but upgraded from 6 and it's KVM virtual machine. There it works correctly via init.d script and the proccess is named /usr/sbin/knotd -d -c /etc/knot/knot.conf

Do you have an idea why it's working on older machine correctly and on the second with OpenVZ not?
Thanks for any help.
