Petr: I haven't been able to reproduce this.

What you run 'service cups stop', what output do you get?  What about when you run 'lpstat -p' at that point (after you've stopped the service)?

Comment 5 Tim Waugh 2012-07-18 08:14:13 UTC

What does 'systemctl status cups.socket' say?

Comment 9 Petr Sklenar 2013-06-20 12:18:34 UTC

it does not produce any issue now:

I guess it was somehow solved by systemd , tried RHEL-7.0-20130606.0 Server x86_64
