Took a look, and it's one of the usual stupid cases of "let's just flood it with things and exit will take a while". In this case it's adding a ton of classic provided buffers, and then exit takes a while to prune them. Not convinced there's a real bug here, outside of the config have lots of debug options that slows everything down. It'll finish eventually, it'll just take a while with how it's being used. -- Jens Axboe
