SIGKILL will be sent to the process, and then syslog-ng will be started again.

Some example messages seen in the syslog during the restart are:

INFO Process PID = 7216 is killed, signal SIGKILL sent successfully,
path = /opt/bin/syslog-ng -F -p /var/run/master-syslog-ng.pid -f
/etc/syslog-ng.conf.
