I'm getting above error on heroku logs. I don't understand the solution and why this error occur.

My server confirmation is high -

  1. Professional Dynos
  2. 2X Worker
  3. Premium Redis Plan - ($15)
  4. Database is - Standard 4 Plan

But still getting this error

I suggest you to see the code with Name.all.each do |block| and change it to Name.find_each do |block|. This way you can save memory by not loading entire model all at once.

Also try running some benchmark tests so that you can find memory leaks that are causing R14 errors.
