Puma with Padrino, CPU consumption will not stop

I have one problem which I am trying to solve, I have Ruby web project, written in Padrino, it is quite simply project. But I have problems with running the Puma.

Everything works fine, but after a few days, or if I make a stress test, the process of Puma is consuming 100% CPU and stays there forever. I need just to restart Puma (resp. kill it and start again).

It is happening on a few my projects, on Debian Stretch and Jessie.

Puma version is 3.11.4

and this is one of the config files:

preload_app!

rackup 'config.ru'

environment 'production'

daemonize
pidfile 'logs/osadababa.pid'

state_path 'logs/puma.state'
stdout_redirect 'logs/stdout', 'logs/stderr', true

threads 4,6

bind 'ssl://0.0.0.0:8060?key=/etc/letsencrypt/live/osadababa.cz/privkey.pem&cert=/etc/letsencrypt/live/osadababa.cz/fullchain.pem'

tag 'osadababa-dev'

I am desperate to know why and solve this annoying problem, I tried to play with configuration, without success. Now two of the processes are at 100%, but the website is working, just draining resources.

Have you some experience like this? Please any suggestions.

I am running ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

Using Puma from Debian package distribution. I will try the upgrade and I will try to create a simple project to test whether the problem will appear too.

Solution
