With only this amount of information, it's hard to say anything useful. A well-behaved named should not hang like that; if you can find out the root cause for that, we can talk about the problem in more concrete terms.
If your named stops serving requests, nslookup will time out; obviously, no web traffic to the server can take place by using the server name in that situation (whereas requests by IP address should continue to work, as such).

POLYGRAPH-DNS-CFG(1) User Commands POLYGRAPH-DNS-CFG(1)
NAME
polygraph-dns-cfg - DNS server configuration tool
SYNOPSIS
dns-cfg [--option ...]
DESCRIPTION
Given a zone name, DNS names, and IP addresses, dns-cfg builds configuration suitable for use with BIND and, perhaps, other DNS servers.
Dns-cfg output consists of three parts. The first part is the text to cut-and-paste into BIND's named.conf file. This part is sent to the
standard output. The outer two parts are direct and reverse zone files. Those may be quite large and are dumped on disk into the appropri-
ately named files. Dns-cfg can use PGL configuration as the source of information.
OPTIONS
--help list of options
--version
package version info
--config <filename>

--cfg_dirs <dirs>
directories for PGL #includes
--zone <str>
