I highly suspect that I am seeing a similar bug with the same core symptom.
We are not using nscd, but with the same content in /etc/nsswitch.conf and a disappearing nis master, any lookup of local (e.g. root) users hang. Killing the nis client or removing the nis-entry from nsswitch.conf rectifies the problem immediately. This causes long hangs in postfix, root logins and similar cases.
The above is with hardy server, which is supported until 2013.
