I just downloaded and compiled the latest Git and a little after starting freeswitch I'm getting non stop the following:

it's non-stop and doesn't let me do nothing else. After the first time I went on to vars and changed the 1234 password....restarted and same thing happened, I also try denying the ip on acl.conf (not sure if has something to do with it but gave it a try):

<configuration name="acl.conf" description="Network Lists">
        <network-lists>
          <list name="test2" default="allow">
            <node type="deny" host="212.224.71.236" mask="255.255.255.0"/>
          </list>
        </network-lists>
      </configuration> 

Restarted the computer but nothing, he (thomas I guess) was back on my console.
Any ideas??? p.s. My computer is on DMZ (I know DMZ is not ideal but is the only way I got to be able to connect to the internal profile from out of the office etc).
