This happens irregularly with TelstraClear's

name servers, and has done so for years. Sometimes I get fed up and add
an xtra server to /etc/resolv.conf, though since I'm using the
firewall's caching name server such problems disappear.

I presume using nscd (name service caching daemon) will also fix that;
but DNS caching seems to be disables by default (SUSE at least) because
they weren't secure enough. Caching of user/group names, yellow pages
nis stuff etc is still on by default.

Try using a different secondary name server.
