https://github.com/bluejekyll/trust-dns/blob/main/crates/server/src/server/server_future.rs#L95

join_next() is never called on inner_join - hence the inner_join will keep growing per dns-request

@jeff-hiner any chance you could look at this? I think it’s related to some of your changes. Could you verify if it’s an issue?

Yeah we need to eventually clean these up. I'd normally suggest doing a lazy try_join_next right after that spawn, but that doesn't exist. Maybe a now_or_never wrapper around join_next, in a loop?
