>Description:
rpc.lockd uses udp ports 631 on startup before the cups daemon starts. This will cause the following error messages on /var/log/cups/error_log "StartBrowsing: Unable to bind broadcast socket - Address already in use." it will prevent the client enable to print on the server.

# sockstat |grep 631
root     cupsd      685   0  tcp4   *:631                 *:*
daemon   rpc.lockd  554   3  udp4   *:631                 *:*
root     rpc.lockd  547   3  udp4   *:631                 *:*

# cat /var/log/cups/error_log 
"StartBrowsing: Unable to bind broadcast socket - Address already in use."

I try to kill the rpc.locdkd daemon and restart the cupsd similar below.

option1: login as root
# killall rpc.lockd
# socket | grep 631
root     cupsd      685   0  tcp4   *:631                 *:*

# /usr/local/etc/rc.d/cupsd restart
# rpc.lockd
# sockstat | grep 631
root     cupsd      959   0  tcp4   *:631                 *:*
root     cupsd      959   2  udp4   *:631                 *:*

# sockstat | grep rpc.lockd
daemon   rpc.lockd  982   3  udp4   *:870                 *:*
daemon   rpc.lockd  982   4  tcp4   *:948                 *:*
daemon   rpc.lockd  982   5  udp6   *:869                 *:*

daemon   rpc.lockd  982   7  dgram  -> /var/run/logpriv
daemon   rpc.lockd  982   9  udp6   *:867                 *:*
root     rpc.lockd  981   3  udp4   *:870                 *:*
root     rpc.lockd  981   4  tcp4   *:948                 *:*
root     rpc.lockd  981   5  udp6   *:869                 *:*
root     rpc.lockd  981   6  tcp6   *:947                 *:*
root     rpc.lockd  981   7  dgram  -> /var/run/logpriv
root     rpc.lockd  981   9  udp6   *:867                 *:*

I also went to single usermode by typing "shutdown now", then exit and check the cupsd and rpc.lockd the problem disappear. But when you restart the server I still have this conflict. 

btw: I only have this error specific to this machine I don't have any error on the other servers.
>How-To-Repeat:
Rebooting my server several times woun't solve the problem as per the suggestion by Christopher Sean Hilton on FreeBSD 5.4.

Killing the rpc.lockd and restart the cuspd or going to single usermode that's the time my server works ok.
