>Description:
The rc script of arpwatch sets the arpwatch_interfaces variable to an empty value and then calls load_rc_config. But if _rc_conf_loaded is true when the rc script is executed, and this happens upon reboot, the value of variable arpwatch_interfaces is set by rc.conf, then it is cleared in the rc script and then the call to load_rc_config does not reload its value. The result is that if arpwatch_interfaces is set in /etc/rc.conf to a list of two or more interfaces then upon reboot, the script misbehaves and only one process is started.
>How-To-Repeat:
Install arpwatch, set arpwatch_enable="YES" and arwpatch_interfaces="fxp0 fxp1" in /etc/rc.conf and reboot the machine. Then check thath only one arpwatch process is running.
>Fix:
The following simple fix solves the problem.
