Web requests get super-slow after running a while
This is somewhat masked by nginx-caching proxy, but nonetheless very noticeable and grating.
This is caused by dnsname-plugin inside rootless-cni-infra
container. Contents of /run/containers/cni/dnsname/ci-deploy/addnhosts
reveal multiple old and invalid entries for dns.
Those will cause a seemingly random amount of delay, as dnsnames will be tried by proxy in different order each time.
