Segmentation faults running in rufus-scheduler - ruby-on-rails-3

Question

I have an application that uses rufus-scheduler to run a variety of background tasks. After recently upgrading to Ruby 1.9.2, we continue to have intermittent segmentation errors and/or bus errors. The error will occur in different libraries.
The one thing that I've identified is that the same functions that will cause a segmentation fault when running under rufus-scheduler will NOT fail when run from a console.
This occurs on two platforms (OSX for development, ubuntu for production) in the same way.
Does anyone have any ideas on what differs in the runtime between the rufus-scheduler environment and running something straight from "rails c" console?
Thanks in advance...

Answer 1

You seem to imply it worked with Ruby 1.8.x. What Ruby 1.9.2 patchlevel anyway ?
Rufus-scheduler is a very dumb library, you could replace it altogether with things like
Thread.new do
loop do
sleep 60 * 60
trigger_my_hourly_task
end
end
Thread.new do
loop do
sleep 24 * 60 * 60
trigger_my_daily_task
end
end
and see if the problem still occurs.
There is no rufus-scheduler environment, rufus-scheduler is pure-ruby, it lives in the environment of your server and your rails application. Running things in the "rails c" console is running stuff in a brand new process, with no accumulated memory usage, it's "blue sky".
If you really think it's a rufus-scheduler issue, you should be able to come up with a detailed way of reproducing the issue.
