Transfers not working

[Mikhael47]

I have a Bind 9.2.1 server setup with another one as the slave.  If the
refresh limit is hit and the serial number on the master is
incremented, the transfer does not occur.

Here is what my zone file looks like

$TTL 86400
@       IN      SOA     dns2.versaterm.com.  root.localhost (
                        7 ; serial
                        30 ; refresh
                        7200 ; retry
                        604800 ; expire
                        86400 ; ttl
                        )


dns2    IN      NS      198.73.216.183
@       IN      NS      198.73.216.183
