Can you please attach more information?
1. attach your /var/log/messages when your named hangs to bugzilla
2. install bind-debuginfo
3. attach named process with gdb (gdb attach <named_pid>)
4. in gdb run "t a a bt full" and attach output
You can attach both outputs as "private attachment" if it contains private data. They will be invisible for other users.
Thank you in advance!
