pg.rb segmentation fault [Mojave upgrade]

Question

Segmentation fault in pg.rb:56

versions: rails: 5.2.0, ruby: 2.4.4, pg gem: 0.20.0

After upgrading to Mac OS mojave i have encountered problems with my local host server. The server itself, starts fine, however when trying to access it through a web browser, it crashes and I have the segmentation error shown above.

Answer 1

As this issue is only occuring in the development environment, I made it conditional. This solution in puma.rb works for me until the bug gets fixed.

workers ENV.fetch("WEB_CONCURRENCY") { 2 } unless Rails.env.development?

Answer 2

in .env file set WEB_CONCURRENCY=0 and you do not need to add any logic in config/puma.rb
