Somehow I missed this information, can you do a lsof and filter just the 
process that is handling the DNS requests (the one that you get from 
netstat -anp | grep 53).

It could be related to this bug: 
https://bugzilla.samba.org/show_bug.cgi?id=8878

In a nutshell I suspect that our server sends forward requests to the 
forwarder that are never answered and the connections piles up, once we 
reached the limit (1024 ?) the server didn't accept any new connections.
