Hmm, (128+129)*88*2 == 45232, (2 == UDP + TCP) so the big number looks plausible. The 21000 limit comes from a hardcoded value for ISC_SOCKET_MAXSOCKETS. You can adjust -U (number of listeners) on the command line to avoid hitting the fixed MAXSOCKETS limit, and leave -n (max sockets) unset, at its default. You can also set ISC_SOCKET_MAXSOCKETS at build time, if you can work out how to wrangle the build system :-) Tony. -- f.anthony.n.finch <d...@dotat.at> https://dotat.at/ Fair Isle, Faeroes: Southwest 6 to gale 8, occasionally severe gale 9 in Fair Isle, veering northwest gale 8 to storm 10. Rough or very rough, occasionally moderate at first in southeast Fair Isle, becoming very rough or high. Rain, squally showers later, wintry in Faeroes. Good, occasionally poor. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
