Segmentation fault

[mario-amazing]

I have Segmentation fault error in the sidekiq container:

    rails (7.0.6)
    parallel (1.23.0)
    sidekiq (7.1.2)

Docker image: FROM ruby:3.2.2-alpine

Any ideas how to fix it?

I'd say try running without yjit and see if that is better.
Otherwise reproduce in a minimal example to see if it's really parallel causing that or just fork.

[mario-amazing]

@grosser, without yjit I have the same error.

With threads everything is fine
{ in_threads: Etc.nprocessors }

[grosser]

try running the same code with just fork to see if this is a ruby bug or a parallel bug

[grosser]

and try to build a minimal example so it's easy to reproduce/debug

[mario-amazing]

I've tried parallels in_processes and fork in console. Everything is fine. But this issue is rare on the production server and I don't know how to catch it. => Only errors in the log file

[grosser]

it looks like the is running in sidekiq which means it's also running in parallel threads already right ?
maybe a solution is to use Thread.exclusive to eliminate that ?
... other idea would be to "dumb down" whatever it does inside, so instead of writing to disk/db just return a string and then write that in serial after the block, basically reduce the block to the essential slow part and do the rest outside

[mario-amazing]

This is a separate sidekiq docker container.
Inside of parallel execution: external API request and handling data from it

[grosser]

maybe the api requests could be done in parallel threads and then data processing in forks

[tisba]

it looks like the is running in sidekiq which means it's also running in parallel threads already right ?

I'm also seeing this from time to time, but wasn't successful yet to cleanly reproduce this.

maybe a solution is to use Thread.exclusive to eliminate that ?

I think Thread.exclusive has been deprecated a long time ago and was removed some time ago (at least in recent Rubys it is no longer available). Where would you apply a mutex exactly?

In our case, we are using processes, as the task we're doing is pretty CPU intensive and benefits greatly from true parallelism. I suspect that some combination of Sidekiq's threads + forking from parallel triggers an issue in some cases, especially if there are multiple sidekiq threads doing Parallel.map(in_processes: …). This also seems to cause parallel's processes to hang sometimes, but again, wasn't able to reproduce this outside of production and troubleshooting this is pretty messy currently 😢

[r7kamura]

I also run into this issue quite often.

Just to share a bit more information in case it helps: in my case, it tends to occur frequently when running RuboCop. It doesn’t happen every single time, but it seems to become more likely as the level of parallelization increases. For example, when running RuboCop on a project with a few thousand files, this issue occurs almost 100% of the time. All of these runs are inside Docker.

Segmentation faults often occur, but sometimes instead, I get strange exceptions at the Ruby level (e.g. NoMethodError), and the content of those exceptions is generally different each time.

I haven’t been able to prepare a minimal reproducible example yet, and I’m sorry, but I haven’t analyzed whether this issue stems from a bug in fork or from the parallel gem.

[grosser]

would be great to see if this can be reproduced with plain fork, because then we found a ruby bug :)
