I have the same error in my logs. Running 2.2-RELEASE (i386). I am very sure there is no other DHCP server on this lan but pfSense. The range is 20 addresses. 100-120

I ran DHCPLOC to be sure. Below I asked for a new OFFER several times.

As you can see only pfSense (10.3.15.1) answered.

The statement " Can't bind to dhcp address: Address already in use" is curious. I also checked /etc/inetd.conf
and it contains:
tftp-proxy dgram udp wait root /usr/libexec/tftp-proxy tftp-proxy

I am seeing this alot .. not just at startup

Any Ideas?

I'm not seeing it. For anyone running 2.2 and having issues my (perhaps obvious and not helpful) recommendation is try 2.2.1

I had the same error message as well, I fixed it by disable DHCP on all interface, make sure DHCPD is gone from services list. then enable DHCP again.

when I had the issue, services would show DHCPD is running, but clients do not receive IP, I see the same error message every time I restart DHCPD. the problem started after I setup HA and upgraded from 2.2 to 2.2.1. I am not sure which action triggered the issue.

robinxyz - You are the Man!!! Funny how rebooting didn't solve the problem but following your steps does. I had installed a 2.2.1 on my test box and was about to replace the production unit with it when I saw your response.

Thanks

norspang

I have this problem too, i have no other DHCP servers running either on the box or on the LAN

I made a fix to this by adding the package 'cron' and applying a job every 15 min with

/usr/bin/killall -9 dhcpd && /usr/local/sbin/dhcpd -cf /var/dhcpd/etc/dhcpd.conf -lf /var/dhcpd/var/db/dhcpd.leases

it is not a nice way but it works for now

norspang

have anyone found a better solution than the fix i made?

robinxyz

the "disable DHCP on all interface, make sure DHCPD is gone from services list. then enable DHCP again." method worked for me, and I have not had problem with DHCP since. Have you tried that?

I know this is a Old topic.

but i got the same error.

I do have an HP all in 1. I did do a scan and a print around the time when this happend. and when i wanted to go a website it didnt work when i checked in pfsense Unbound stoped. I could just start it again without any problems.

i will do when i get back another test where i turn on the printer and see if it will stop unbound again. i normally dont have the printer powered on at all only when i use it so i never had this Unbound problem.

if it does kill unbound again when i give a command to the printer/scanner then that is the problem. But no idea how to solve that.

norspang…thanks for your cronjob...it has saved me a lot of hassle...not ideal but gets the job done.
