As others asked, please clarify a bit more what "hang" means.  I'd
particularly interested in
 - whether it responds to rndc (e.g. rndc status)
 - whether it responds to queries for build in data, such as
   version.bind/TXT/CH (try 'dig @server_address version.bind txt ch'
   from the local host).
 - if you enable XML based statistics, whether it responds to
   statistics request over http.  If it does, showing the xml
   statistics while the problem is happening would be useful.

Please also make sure you kernel doesn't have this problem:

If you are not sure, and if the query load is not so heavy, (e.g. up
to 2000qps or so), you may also want to try rebuilding named with
--disable-devpoll
