2513	nginx resolver issue	bsiara@…		"nginx (openresty 1.21.4.1) is compiled in docker alpine 3.17, in nginx.conf in http block I have a delcaration of resolver

{{{
resolver 192.168.1.1 ipv6=off;
resolver_timeout 10s;
}}}

Sometime (aproximetly one time for week) nginx resolver behave strange. In upstream I have a name which is refreshed every 300s to the new A records. Sometime nginx does not resolve this name to new records and still resolve to old A records. In this situation reload fix the issue, but this is not a solution. This happends only for one name at a time which is refreshed."	defect	closed	major		nginx-core	1.21.x	worksforme			Linux ec1-prd-k8s-nginxfront-1 5.15.0-1036-aws #40~20.04.1-Ubuntu SMP Mon Apr 24 00:21:13 UTC 2023 x86_64 Linux	"built by gcc 12.2.1 20220924 (Alpine 12.2.1_git20220924-r4)
