Bug #17781: Resolv::DNS RequestID table allocations are never freed, causing DNS lookups to eventually hang - Ruby master - Ruby Issue Tracking System

Sidekiqを長時間走らせておくと処理が止まる原因はこれかもわね…
@zundan Oh!!!
Is this the problem everyone's been having?! How did you manage to find it?
And I never noticed it because I'm still using 2.6.6 in production...
@Gargron I've just noticed this Ruby's bug in a PR to a work related code, while I personally haven't been able to reproduce Sidekiq hanging after a while as Heroku restarts processes every 24 hours.
