Answer 1

I had a similar issue, in which my test environment was often crashing in Ruby 2.6.3 with Segmnentation Fault lib/pg.rb line 56.

What worked for me was setting pumb.rb to have zero workers in the test environment:

# config/puma.rb
(ENV.fetch("RAILS_ENV") == 'test') ? (workers 0) : (workers ENV.fetch("WEB_CONCURRENCY") { 2 })
