Failover problem with 4.2 on FreeBSD

[Ivan Lago]

Hi to all

I have a problem with a test installation of version 4.2, with failover
active, on FreeBSD.
I have tested it against FreeBSD 6.x and 8.x, with both chrooted daemon and
without chroot,with the same results:

if i put both the daemons in foreground mode with -d, everything works fine,
and i see the pools balancing between the servers; if i put even one of then
in daemon mode, failover stop working and i see the one in foreground going
to communication-interrupt and never recover the failover connection.

One thing i noticed is this: if failover is working (both servers running in
foreground) i see those sockets on the machines:

on the primary:
dhcpd    dhcpd      3411  9  tcp4   85.239.184.101:647
85.239.184.123:27190
dhcpd    dhcpd      3411  10 tcp4   85.239.184.101:647    *:*

on the secondary:
dhcpd    dhcpd      2687  9  tcp4   85.239.184.123:27190  85.239.184.101:647
dhcpd    dhcpd      2687  10 tcp4   85.239.184.123:647    *:*

As you can notice the remote port on the secondary is the same on both
connections.

If i daemonize one of them or both, i see:

on primary:
dhcpd    dhcpd      3491  9  tcp4   85.239.184.101:50468  85.239.184.123:647
dhcpd    dhcpd      3491  10 tcp4   85.239.184.101:647    *:*

on secondary:
dhcpd    dhcpd      2744  9  tcp4   85.239.184.123:57089  85.239.184.101:647
dhcpd    dhcpd      2744  10 tcp4   85.239.184.123:647    *:*

What can the cause be?

Thanks in advance for any help
