Description

I have a simple sidekiq job running http request through net/http lib, many years (no issues with ruby 2.3-2.7.2), last week i upgraded to ruby 3.0, that simple job raise the following exception after running every 10+ hours, (restart sidekiq process will solve the problem), so I looked the error log, most of them are killed by the Timeout.timeout block when calling resolv.getaddress, raise the "execution expired" excepiton. dig in the thread deadlock may happened on resolv.rb:620, during the allocate_request_id. I have no experience on digging these thread issues, not sure what the root cause will be.
