Hi Pavel
is fastnetmon detaching all the ZC resources on Ctrl+C? Could you reproduce it with our sample applications?

Thank you

Hi Pavel
it is still a problem with the applicaiton, not with the library: zcount was not shutting down correctly in case of wrong interface,
please try reproducing it with latest commit:
