Next time when it happens can you do this:
netstat -anp | grep 53 to get the pid of the samba process that is 
listening on port 53 then do
gdb -p <pid>
bt full
thread apply all bt full
info locals
generate-core-file /tmp/core_for_dns

And send to the list the info, keep the corefile in a safe place and 
send it upon request to one of the samba developer.
