\u0421\u0432\u043e\u0434\u043a\u0430:

SELinux is preventing /sbin/setfiles access to a leaked packet_socket file
descriptor.

\u041f\u043e\u0434\u0440\u043e\u0431\u043d\u043e\u0435 \u043e\u043f\u0438\u0441\u0430\u043d\u0438\u0435:

[restorecon \u0437\u0430\u043f\u0443\u0449\u0435\u043d \u0432 \u043f\u0440\u0438\u043d\u0443\u0434\u0438\u0442\u0435\u043b\u044c\u043d\u043e\u043c \u0440\u0435\u0436\u0438\u043c\u0435
(setfiles_t). \u042d\u0442\u043e \u0434\u0435\u0439\u0441\u0442\u0432\u0438\u0435 \u043d\u0435\u0434\u043e\u043f\u0443\u0441\u0442\u0438\u043c\u043e.]

SELinux denied access requested by the restorecon command. It looks like this is
either a leaked descriptor or restorecon output was redirected to a file it is
not allowed to access. Leaks usually can be ignored since SELinux is just
closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the packet_socket. You should generate a bugzilla on selinux-policy,
and it will get routed to the appropriate package. You can safely ignore this
avc.

You can generate a local policy module to allow this access - see FAQ
