How to restart Sidekiq when running on Heroku?

Question

I am running sidekiq in a worker on Heroku as follows:

bundle exec sidekiq -t 25 -e $RAILS_ENV -c 3

One of the operations uses more memory (>500mb) than the worker allows. After the job has completed, the memory still hasn't been released and I get these errors in the heroku rails log files:

2018-11-13T00:56:05.642142+00:00 heroku[sidekiq_worker.1]: Process running mem=646M(126.4%) 2018-11-13T00:56:05.642650+00:00 heroku[sidekiq_worker.1]: Error R14 (Memory quota exceeded)

Is there a way to automatically restart Sidekiq when the memory usage exceeds a certain amount?

Thanks!

Answer 1

have you tried to reduce memory fragmentations? here how you can do it in Heroku.

if that wasn't good enough you can use Heroku platform gem and periodically restart the sidekiq
