Hi Nick, IIRC, unbound does a “bind before connect” on sockets, which requires a local port to be completely unused [1] to be used by bind.
Unbound 1.6.4 should fix this by setting SO_REUSEADDR on outgoing ports - please give it a try. Kind regards Quirin [1] https://idea.popcount.org/2014-04-03-bind-before-connect/ > On 06 Jul 2017, at 10:13, Nick Urbanik via Unbound-users > <unbound-users@unbound.net> wrote: > > Dear Folks, > > A DNS server running unbound 1.6.3 has these messages; any suggestions > on what is happening? > > error: serviced_tcp_initiate: failed to send tcp query > error: outgoing tcp: bind: Address already in use > -- > Nick Urbanik http://nicku.org 808-71011 nick.urba...@optusnet.com.au > GPG: 7FFA CDC7 5A77 0558 DC7A 790A 16DF EC5B BB9D 2C24 ID: BB9D2C24 > I disclaim, therefore I am. — Dipl.-Ing.
