undefined method `supervisees`for nil

[wdiechmann]

https://github.com/rails/solid_queue/blame/c521c6d47d10abeaf076a81d9af29e80eb2b11c7/lib/solid_queue/supervisor.rb#L174

probably should look something like process&.supervisees.find_by... or

if registered_process = process.supervisees.find_by(name: terminated_fork.name) rescue false

[rosa]

Huh, yes, but I'm curious to know when you reach this line with process being nil 🤔 In theory, this should never be executed before the supervisor has been registered. I must be missing a scenario where this might happen, but not sure what it'd be. Do you have more context about when you hit this?

[wdiechmann]

I got the background job to work - 99% thx to you - and then I let it rip for a few hours - and once I got back to my desk, the log told me that there where no supervisees hanging out with the nil process 😉

I'll make sure to try to sample better context when this happens again - if it does

[HashNuke]

Just found this issue. I only have the occassional jobs to send an email. Nothing that adds to load.

Environment information

• Development environment
• Procfile has this line to start jobs -jobs: bin/jobs start
• The only config related to solidqueue in my development.rb are these lines

  config.active_job.queue_adapter = :solid_queue
  config.solid_queue.connects_to = { database: { writing: :queue } }

I just got this error again, this time I saved some additional events from the logs immediately before the error.

Just posting it here so that I can come back to debug this later.

[rosa]

Thanks a lot for these extra logs, @HashNuke! These are very helpful as I haven't been able to reproduce this 🙏

[tahirwaseer]

@rosa I'm also running into this quite frequently, maybe three or four times daily. Posting the logs if they are helpful.

Setup:

• solid-queue-1.1.0
• rails 7.1.2
• ruby 3.2.0
• Docker container
• env=development
• enqued 1000s of jobs
• I'm running 3-4 workers with this config for each of them

default: &default
  dispatchers:
    - polling_interval: 1
      batch_size: 500
  workers:
    - queues: "*"
      threads: 3 # You can manage these threads by altering the connection pool for puma, n-2 is the formula is followed for solid queue threads, where n is the no of connections for puma
      processes: <%= ENV.fetch("JOB_CONCURRENCY", 1) %>
      polling_interval: 0.1

I'll try with the latest release later.

Oh! @tahirwaseer, that's very interesting because you're hitting a different error (besides this one), that SEGFAULT in the supervisor. Do you know where that comes from exactly? It needs to come from either Ruby or a gem that uses C extensions. Wondering if the SEGFAULT is causing the other bug... 🤔

[tahirwaseer]

These are almost all the logs. other didn't look relevant. It keeps processing the jobs and after a while i get this. Haven't figured out the exact reason.

One more thing about the setup:

I've this in my puma.rb:
max_threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }

And I'm running four workers with three threads each which exceeds puma threads. Not sure if this could cause anything like that.

Got another one:

[tahirwaseer]

I'm running on latest solid_queue and have simplified the configuration.

• increased max thread count on puma to 12
• set worker threads to 8
• running only one worker

The docs are not super clear but I think solid_queue needs two additional threads to run scheduler etc. other than the worker process. Which should correlate with puma threads. Now puma has enough capacity to handle everything. = ??

This is the most frequent error that I'm getting. something linked to concurrency.

Vaguely I feel like this has happened during database migrations or when I have reseeded my database, but it's perplexing because this is a very small, brand new app with not a lot going on. Every once in a while I find myself having to start the server back up and it's because of this error.

[kofiasare-dev]

Same here

[rosa]

Oh, @kofiasare-dev, thanks for that! That's interesting because you're running multiple supervisors in the same machine 🤔

Did this happen when you woke up your computer after it had been suspended? I think the only way this could happen is if, somehow, the processes are suspended and fail to send heartbeats, then suddenly wake up and they're dead and so their registered processes get wiped up under them in an ungrateful way. This wouldn't happen in a real production setting.

[tahirwaseer]

just to confirm @rosa. I've been running the server and job processes on the same container. maybe that could explain it?

I can spin up a separate container for processing jobs and test there; that should replicate close to production env.

[rosa]

@tahirwaseer, no, that should be ok, what I mean is that in production usually your processes won't go "to sleep" like if you have them running in your computer that might be suspended after some time inactive 😅
