Workers crash when processing jobs #115

I have a job that I run during the night for each of our users. I'm attempting to queue the job with Resque and process them with Sidekiq to ease the transition.

Here is the job:

class MatchesAlgoForAlertsJob
  include Sidekiq::Worker
  @queue = :nightly

  def perform(user_id)
    user = User.find(user_id)
    Algorithm.matches_algo_for_alerts(user)
  end
end

It appears as though it starts to process them and then dies. The rescue worker has always worked.

This looks like you're using mongo mapper here. Is that library thread-safe?

@mperham
Owner

It looks like the Processor is running out of stack. This could be caused by infinite recursion in your worker. Second stack shows a problem with the manager that I haven't a clue how could happen. @tarcieri might need to swing by and lend us his wisdom.

@brandonhilkert
Collaborator

Good question about it being thread-safe....I'll reach out to the maintainer to confirm.

@brandonhilkert
Collaborator

Haven't heard back, but from poking around message boards and event machine gems, it would appear that MongoMapper is not thread-safe. Guess this is a deal-breaker huh?

@krainboltgreene

Mongoid is working on being Threadsafe it seems: mongoid/mongoid#1291

@tarcieri
Collaborator

Celluloid runs all methods in fibers, and it looks like you're exceeding the 4k stack size limitations that fibers impose. That's orthogonal to the issue of not using a thread-safe library, which won't work either.

A quick fix is to try to run the code outside of a fiber using defer { ... your code here ... }, however that won't help you if it's not thread safe.

@fbjork

Try using the Ruby mongo driver directly and see if that helps.

@mperham
Owner

I know this sounds crazy, but you could also run Sidekiq in single-threaded mode with -c 1 and see if the error still occurs. You lose all of the benefits of Sidekiq of course but it will tell you if thread-safety is the issue. You'll need to configure Redis like in #116 or use master to make it work though.

@brandonhilkert
Collaborator

It appears that doing one job worked better (it processed many more). Still got the stack error, but after @tarcieri explanation, seems like these jobs in particular aren't the best candidate because it's doing a LOT of crunching that would likely go over the stack size limitation.

/Users/bhilkert/.rbenv/versions/1.9.2-p290/bin/sidekiq:19: stack level too deep (SystemStackError)
@ryanlecompte

That's an unfortunate limitation of wrapping all Celluloid async calls in a fiber. :-(

@ryanlecompte
Collaborator

Hopefully @mperham's old issue for dynamically increasing the Fiber stack size will get some love, although it was filed 2 years ago. :-(

Try master now. I'm unclear on what happens if an error is raised in Processor#stats but @tarcieri and I will figure it out.

@brandonhilkert
Collaborator

Yup, that worked for me when running with -c 1.

I've opened an issue for this on the Celluloid tracker if you'd like to discuss further:

celluloid/celluloid#45

@jackbit

I haven't solution yet, please follow Issue #327: Stack Level Too Deep
