PROBLEM: (94338) (PATCH ID: OSF520-1064)
********
This patch fixes a problem with the IPv6 Neighbor Discovery daemon (nd6hostd)
where under certain circumstances the daemon causes an overlow of the DNS
TTL (time to live).  The overflow is caused only when nd6hostd is configurd
to dynamically update DNS, and the IPv6 prefix lifetimes advertised by an
IPv6 router are set to infinity.  The problem is caused by setting the TTL
for an updated DNS recored too high so that it overflows and is written to
the DNS database as a negative number.  Any subsequent reloads of such a
database will fail.
