I have a rails 4.1 application with Sidekiq 3.3.2 in production mode with default config.
Everything works fine, but sometimes, I see in Sidekiq admin panel that Sidekiq process, not listed in the "busy" in the panel and does not exist in the list of processes. That seems like a sidekiq's process has been fail. In the log there is no error entries.
How can I make that stable?
This is known problem. Hard loaded Sidekiq worker is disappear sometimes from busy list but still working fine.
I known issue marked as fixed but seems like it appear again and again. Just don't worry about it and use ps aux | grep sidekiq
to check running Sidekiq workers in this case.
