		akvadrako on Oct 19, 2017 \| parent \| context \| favorite \| on: Why Ruby App Servers Break on MacOS High Sierra It's been addressed, but it's a hack. To be safe, apps must stop all other threads before forking. The only correct fix I can see is to have pre- and post- fork hooks in every library, which make that guarantee.

In Puma, we emit a warning if we detect any additional threads running prior to fork.
