[Kamailio-Users] Dispatcher ds_list results in flag=P

[Geoffrey Mina]

No, I am not seeing any options messages.  It doesn't appear to be
doing anything while in probing mode.  How often should an OPTIONS
message go out?

One thing to note, i have two public IP addresses on eht0, so I have
eht0 and eth0:1.  I also have eth1 which is a private network
interface.  I have nothing specified in the kamailio.cfg "listen", so
Kamailio just listens on all IP addresses.  I do not believe this
happened before I added the 2nd IP to eth0.  At that time, i also had
explicit listen parameters specifying the internal and external IP
addreses.  When the configuration was in it's previous state, this
never happened.

One additional bit of info, the servers that are in "P" state are on a
different public subnet.  The servers in "A" state are all in the same
public subnet as the Kamailio.
