Sidekiq is probably the best background processing framework today. At the same time, memory leaks are very hard to tackle in Ruby and we often find ourselves with growing memory consumption.
Highly inspired by Gitlab Sidekiq MemoryKiller and Noxa Sidekiq killer.
Use Bundler
gem "sidekiq-worker-killer"
Add this to your Sidekiq configuration.
Sidekiq.configure_server do |config|
config.server_middleware do |chain|
chain.add Sidekiq::WorkerKiller, max_rss: 480
end
end
The following options can be overrided.
| Option | Defaults | Description |
|---|---|---|
| max_rss | 0 MB (disabled) | max RSS in megabytes. Above this, shutdown will be triggered. |
| grace_time | 900 seconds | when shutdown is triggered, the Sidekiq process will not accept new job but wait 15 minutes for running jobs to finish. |
| shutdown_wait | 30 seconds | when the grace time expires, still running jobs get 30 seconds to terminate. After that, kill signal is triggered. |
| kill_signal | SIGKILL | Signal to use kill Sidekiq process if it doesn't terminate. |
