Actually I think I've found the issue. The two servers are connected via two different ethernet interfaces. I initially setup the Kamailio user with the IP of eth1 and that worked but Kamailio was trying to connect to MySQL using eth0 (which I did not have that IP authorized to connect). By trying to connect over and over and failing, MySQL blocked the connection (http://dev.mysql.com/doc/refman/5.0/en/blocked-host.html).
That sounds like a viable diagnosis!
