https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270824 Bug ID: 270824 Summary: [local_unbound] exceeded the maximum number of sends Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: saper@saper.info This is running 14.0-CURRENT as of ea6d1692666 but I am pretty sure I've se= en this before. For a long time, this road warrior/laptop install has been plagued with unstable DNS resolution. It is almost never possible to quickly change netw= orks (from one WLAN to another one or to USB tethering) and not lose ability to resolve DNS. Even when working on one network for a longer time, I get DNS resolution er= rors in Firefox regularly. Switching to 8.8.8.8 or something given via DHCP usu= ally rectifies the issue. I am pretty sure my tethering DNS server is not hijack= ing the requests. I use "nameserver ::1" in my /etc/resolv.conf Today, when things are really bad, I have enabled some more debug # more /etc/unbound/conf.d/logging.conf=20 server: log-local-actions: no log-queries: yes log-replies: yes log-servfail: yes logfile: /log/unbound.log val-log-level: 2=20 [1681416195] local-unbound[48019:0] error: SERVFAIL <push.services.mozilla.= com.

AAAA IN>: exceeded the maximum number of sends I've tried to follow if this is related to https://github.com/NLnetLabs/unbound/issues/422 but I am not sure. Additional config changes (trying to turn off DNSSEC validation) but they do not seem to help (commenting out "auto-trust-anchor-file" and adding "module:config: "iterator"") $ more /etc/unbound/unbound.conf # This file was generated by local-unbound-setup. # Modifications will be overwritten. server: username: unbound directory: /var/unbound chroot: /var/unbound pidfile: /var/run/local_unbound.pid # auto-trust-anchor-file: /var/unbound/root.key module-config: "iterator" # include: /var/unbound/forward.conf include: /var/unbound/lan-zones.conf include: /var/unbound/control.conf include: /var/unbound/conf.d/*.conf $ more /var/unbound/lan-zones.conf=20 # This file was generated by local-unbound-setup. # Modifications will be overwritten. server: # Unblock reverse lookups for LAN addresses unblock-lan-zones: yes insecure-lan-zones: yes Another log sample: [1681415385] local-unbound[48019:0] error: SERVFAIL <bugs.freebsd.org.
