Are you using RedHat? There is a known problem with bind on RedHat
where the nslookup and dig commands do not exit correctly due to a
kernel pthread issue.
If you are using Redhat, this problem is fixed in nagios-plugins
1.4.2, but you need to compile it yourself for the ./configure script
to pick up that your system has a problem and workaround it.
Alternatively, Sascha Runschke has been working with Red Hat and it
has been fixed in hotfix-kernel-2.6.9-22.12.EL, which you can
probably request from them through your support contract.
