Sidekiq job get stuck in "busy" - ruby-on-rails

For some time now my sidekiq keeps getting stuck and us not executing jobs in my development environment. They are stuck in "busy" and it seems to be arbitrary because I tried it with different jobs and sometimes they run and then they stop, even after restarting sidekiq and clearing the queue with 'redis-cli FLUSHALL`.
I researched and with kill -TTIN pid I got a backtrace but I don't even know what to look for. Find the logs down below.
Other assumptions I have/things I changed before it happened:
I had cron jobs running locally, which worked fine
Changed concurrecny from 10 to 50 and then back to 10
upgraded to Rails 6
Something with redis?
I really appreciate any help, as it is blocking me :(

For any one running into the same issue:
After upgrading to Rails 6, I didn't change the auto loader to zeitwerk by mistake.
Find some more information here: issue on Sidekiq repo
Change this in:
# application.rb
...
config.load_defaults "6.0"
...
You can also test if you have zeitwerk enabled with
rails zeitwerk:check

Cuttlefish SMTP process crashes at mail send test

I am launching Cuttlefish (https://cuttlefish.io/) SMTP process like this:
bundle exec rake cuttlefish:smtp RAILS_ENV=production
But when I try to send the test mail thru Cuttlefish's web, this process crashes with this last message:
Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (ECONNREFUSED)
What am I missing? Cuttlefish is connected to a MySQL DB, and this seems to be OK. Also, I have Postfix on the same machine, which has also been tested OK. How to make this SMTP process work?
Here is the full crash stack:
I'm listening for emails via SMTP on 0.0.0.0 port 2525
I'm in the production environment
rake aborted!

Your app is failing due to redis connection, check if you are using redis in some module and install redis or else remove redis dependency
I solved the problem by launching Redis server:
redis-server&

Rails throwing a Redis::TimeoutError

I have tried twice to install an installation of RubyMine on a CentOS7 VM. They have now both failed due to a Redis::TimeoutError.
I have received this error when attempting to start the rails server. This happens both through RubyMine and through the Konsole after I start redis through the "service redis start" command.
I can start the rails server fine without starting redis first. And the application works fine (so far) if I start redis after the server starts. However this is only a short term solution as I will be adding automatic start for all services such as redis when my VM starts.

'delayed_jobs' gem not migrating on heroku

Please see update at bottom
I'm trying to use the 'delayed_jobs' gem in my project. I got everything working in my local environment, however when I moved the project to production on Heroku I was unable to 'rake db:migrate', and am not able to get my server started. Here are the steps I followed.
*Run bundle_install with 'delayed_job' and 'delayed_job_active_record' in my gem file
*I did not run 'ails generate delayed_job:active_record' as the migration file was moved to the server from when I ran 'ails generate delayed_job:active_record' in DEV
*I ran rake db:migrate and it failed with the following error, not sure how to fix. (Note: It appears that the migration is failing due to the table not existing, which is a big issue as I need to run the migration to create the table).

UPDATE
I figured out the problem was caused by executing the following code at the initialization of my rails app. I was able to get the migration to work by temporarily removing it, and then adding it back in after the migration was complete (the code require the migration to be run before it was run). This is a temporary patch so I am going to work on getting a better solution for future PROD pushes. I'm thinking I can find a way to check if the table exists before running the code, but if anyone knows of a better way please let me know.
system("ruby lib/background_job start")
SquareOrderCleanupJob.set(wait: 10.minute).perform_later()
at_exit do
system("ruby lib/background_job stop")
end
You can check if a table exists, and therefore if migrations have been run:
ActiveRecord::Base.connection.table_exists? 'table_name'
That answer is also in SO here.
