Hello

I'm running a Rails 4.2 app in production with chruby 0.3.9 and Ruby 2.2.1p85 on Ubuntu 14.04TLS.
I have several unicorn and workers processes.
I got this crash on my cron jobs several times

This [1] seems to be the section of the code where the error happened.

@ko1 (Koichi Sasada): Could this be a GC issue?

This might be a duplicate of https://bugs.ruby-lang.org/issues/10933 which has already been fixed (but not released)?

[ko1 (Koichi Sasada)]

Could you check it on the latest version?

I'm experiencing the same issue under ruby 2.2.2p95 . Full stack trace attached:

Do you know how to reproduce it?

Rails+Ruby 2.2 isn't enough for me to make a crash.

I was able to reduce the frequency by updating some gems. Now, instead of happening in different cases, it only seems to happen on routines that fetch data from an external API's ( yammer and Diigo ).

Going to have a look in more detail if I find a common denominator.

Can't you compile with debug symbols enabled?

I have recently experienced two crashes (stack traces attached) that appear similar to Mr. Rigart's. Both appear to involve creation of a new array in methods called indirectly from the block passed to Thread.new.

Both occurred when running cucumber tests in a rails app. Unfortunately I haven't figured out how to reproduce them.

crash_webrick.txt happened under rails 4.1.6 when using webrick as the http server for the tests.

crash_thin.txt happened under rails 4.1.11 when using thin as the http server for the tests.

Upload failed for one of the stack traces I mentioned in the preceding comment. Here is that file.

[nobu (Nobuyoshi Nakada)]

crash_thin.txt seems related to EventMachine.
Maybe it didn't acquire GVL properly.

Same problem for Ruby 2.2.2

Rails 4.2.3
Ruby 2.2.2 (using RVM)
Debian 7.
Stack trace: https://gist.github.com/noff/4c61cd980c098bba1041
Every cron task dies with such error, but everytime it happens in different files (ssl, new_relic, dependencies, etc).

[mkechinov (Michael Kechinov)]

Problem still happens.
Any news with it?
It happens only on one machine on Debian 7.
Does not reproduce on same machine with same OS.
