>Description:
Even if started with the '-s' option, syslogd(8) will still bind to udp port 514.  It won't actually log messages sent to it (it's possible it would if the packets had a spoofed source address of 127.0.0.1?), but it shouldn't even bind the port, since I might wish to use that port for another application on the system and I explicitly instructed syslogd to not bind it.
>How-To-Repeat:
/usr/sbin/syslogd -s
netstat -a | grep syslog
