Subject: [ruby-core:66818] [Backport200 - Backport #9432] ThreadError [ Attempt to unlock a mutex which is locked by another thread ]

Issue #9432 has been updated by Aaron Stone.


Note: Sidekiq does not appear to be using eventmachine, which has a similar bug at #9132. Any ideas on what is going on here? I can reproduce the bug from all releases of Ruby 2.0.0pxxx including 2.0.0p598.

I use ruby-2.0.0-p247. I seem to get this issue frequently in threaded environment. (Sidekiq) 

I am not very sure if it a ruby thread issue as such or something I am doing wrong. If there is any more details you need I would be happy to provide you.

Operating system: Ubuntu

Trace
