Getting Around OSX Bash Fork Issues
Mar 20, 2017
If you've ever seen this error under OSX:
-bash: fork: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash: cannot make pipe for command substitution: Too many open files
then you know that it usually signals "Oh crap - restart the box". If you're a Rails developer then you may be hitting this due to problems with the new Puma development server and the evented listener.
The solution is to change the listener in config/environments/development.rb from:
config.file_watcher = ActiveSupport::EventedFileUpdateChecker
config.file_watcher = ActiveSupport::FileUpdateChecker
You might also want to kill the listen gem as well (read the linked issue above).
