I hope this helps you . It looks like you are using both minimagick and kraken to do image manipulation. If you fully migrate to Kraken and let them handle all of your image manipulation you shouldn't have a problem with memory on your workers.
Remove all of your versions and see if that improves performance.
code :
version :leisure_358x243, :if => :leisure_theme? do
  process :resize_to_fill => [358,243]
end

it helps some times I've just added HEROKU_SSL_VERIFY=disable to my .bashrc. Unfortunately, I don't know how to fix this in other way. This thing started to appear in my console since I've updated heroku gem to 2.0.5…

I wish this helpful for you Basically, it is how many worker processes you want within each dyno. See here. Each worker process will allow you to run a concurrent request on the same dyno. Each worker process consumes some memory, so more worker processes will make your app run slower. It looks like Heroku recommends 2-4 worker processes, so I would set it somewhere in there. If you don't set anything, it will default to 3, which is probably a good number.
Bottom line: You need to set it to an integer, likely between 2 and 4. Unless you have reason to change it, it's probably fine to leave it with the default of 3.

Puma forks multiple OS processes within each dyno to allow a Rails app to support multiple concurrent requests. In Puma terminology these are referred to as worker processes (not to be confused with Heroku worker processes which run in their own dynos). Worker processes are isolated from one another at the OS level, therefore not needing to be thread safe.
Is Puma WEB_CONCURRENCY on a per Dyno basis for Heroku?

This might help you Yes, the web concurrency is on a per-dyno basis.
Each dyno is an independent container, running on a different server. So you should see each dyno as an independent server.
