Hi Andre, This is curious ‘cos I’ve just been running 2.88test6 for the past 28 days (I was away in Japan for a month and was banned from touching the openwrt router whilst I was away) with stubby without any problems.
My stubby config is different: # Autogenerated configuration from uci data resolution_type: GETDNS_RESOLUTION_STUB round_robin_upstreams: 1 appdata_dir: "/var/etc/stubby" trust_anchors_backoff_time: 2500 tls_authentication: GETDNS_AUTHENTICATION_REQUIRED tls_query_padding_blocksize: 128 edns_client_subnet_private: 1 idle_timeout: 10000 listen_addresses: - 127.0.0.1@5453 dns_transport_list: - GETDNS_TRANSPORT_TLS upstream_recursive_servers: - address_data: 2606:4700:4700::1111 tls_auth_name: "cloudflare-dns.com" - address_data: 2606:4700:4700::1001 tls_auth_name: "cloudflare-dns.com" - address_data: 1.1.1.1 tls_auth_name: "cloudflare-dns.com" - address_data: 1.0.0.1 tls_auth_name: "cloudflare-dns.com” and my dnsmasq config is wildly different, so I’m not sure looking for differences in config is going to help, although I note I don’t validate dnssec instead trusting my upstreams to do it. Try installing & using ’strace’ on the errant dnsmasq to get a flavour of what it’s doing syscall wise, hopefully that will give some clues whilst the clever people on this list come up with better suggestions. An additional idea, enable ‘log-queries’, an idea of the last queries handled by dnsmasq before it goes AWOL might reveal a pattern.
