Sporadic Ruby Crashing

Description

We're experiencing a crash in our Ruby application that is extremely hard to reproduce on-demand, but our application crashes 1-2 times a day. We've place some GC code within our application where we think the problem is occurring. This has somewhat helped, but we still don't have a good idea what code is causing the crash (or even if it's our code at all).

GC.verify_internal_consistency

We have many more crash reports, but I've attached a sample of the latest one. Any suggestions how we could repro this crash to help file a more definitive bug report?

Standard out log:

sample.rb:140: [BUG] inconsistent finalizing object count:
expect 11
but 11 zombies
heap_pages_deferred_final list has 0 items.
ruby 2.3.4p301 (2017-03-30 revision 58214) [x86_64-darwin16]
