OK, so we identified the source. Thanks a lot Alex!

Brian, you could sniff the UDP traffic for MI datagram, are you using 
UDP sockets or unix sockets?

Anyhow, I wonder what the cdrtool would need for rating from kamailio... 
so if you can get the commands send by cdrtool, I can tell you where is 
the possible lock.
