      ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
      OpenSSL 1.0.1f 6 Jan 2014

      Description

      I am running 5 ruby threads on the same server, all making regular calls to mongo using the ssl option and they throw this seg fault around 30% of the time. Any help would be appreciated.

      /opt/rbenv/versions/2.3.0/lib/ruby/2.3.0/openssl/buffering.rb:57: [BUG] Segmentation fault at 0x007fde66b1e550
