newrelic crashes sidekiq web UI about newrelic-ruby-agent

[jasonrclark]

Hey @andreasknoepfle. You'll probably have gotten a note about this from our support staff as well, but I wanted to note things here too for anyone else who encounters a similar problem.

We've identified an incompatibility with the peek-gc gem (https://github.com/peek/peek-gc) which we're looking into presently. In the meantime you can do either of these to work around the error:

1. Not use the peek-gc gem.

2. Patch the agent to disable GC profiling support from an initializer like this...

module NewRelic
  module LanguageSupport
    def gc_profiler_enabled?
      false
    end
  end
end

Sorry for the inconvenience, and I will report back here once we have an agent version that resolves the problem.

[andreasknoepfle]

thank you.
we disabled peek-gc in the meantime and it seems to work fine.

what's the status of the incompatibility ?
Thanks

Hi @salimane - for now, you'll need to use one of the workarounds that Jason mentioned above.

We're planning to address this in an upcoming release of the agent, and also add a configuration setting that allows you to disable GC profiling by the agent. We'll update this thread once that change is released.

Hey @salimane and @andreasknoepfle - the latest version of the Ruby agent (3.9.0, just released today) should fix this incompatibility. Please give it a try and let us know if you're still having trouble. Thanks!

@benweint the new version has fixed this issue.
Thanks
