When I run my rails test suite with the parallel_test gem a thread crashes. The test suite completely passes when I don't run the tests in parallel and it also works fine when I run unit tests in parallel, but if I run enough system tests with rspec using Capybara driven by Selenium using Chrome on a Puma server I always get a crash. On my Mac I'm able to use my computer after the crash, but my Ubuntu 18.04 computer completely freezes up and I have to force it to restart.

It turns out the Ubuntu computer was freezing due to an unstable overclock of the RAM. Perhaps the thread crashed because my code or a library I'm using is not thread safe.
