racoon saying local address is already in use

[Lyle Scott III]

I am trying to setup FreeBSD 6.2 + ipsec-tool + pf to talk to a sonicwall
via vpn

172.16.5.0/24  [lan]---------[freebsd] 66.66.66.66  ----[internet]-----
99.99.99.99 [sonicwall]------ 192.168.50.0/24

I am getting an error in /var/log/racoon.log that 172.16.5.1 is 'already in
use'.  I have verified that there are no racoon processes and start it up to
the same result.  Is there something  I am missing?
