      Have started seeing some strange errors emanating from bson gem when trying to insert a record via Mongoid. Error comes from lib/bson/object_id.id, in the `generate_data` method. The errors are mostly in our background jobs (for now) and they pass usually on the second attempt.

      This issue presents itself in numerous ways:

      • NoMethodError: undefined method `bytes' for an instance of Hash
      • NoMethodError: undefined method `bytes' for an instance of ActiveSupport::TimeWithZone
      • NotImplementedError: method `bytes' called on terminated object (0x00007f522f8b6fe0)
      • NoMethodError undefined method `bytes' for an instance of Datadog::Tracing::TraceSegment
      • NotImplementedError: method `bytes' called on hidden T_ARRAY object (0x00007f5eb2a36ae8 flags=0xc0002a807)
      • ArgumentError: wrong number of arguments (given 1, expected 0)

      All the above have the same stack trace:

      My hypothesis:

      The bson gem `next_object_id` method appears to be calling out to a native c function, `rb_bson_object_id_generator_next`. The error is happening on different objects (hash, array, terminated object). So is it possible that this bson next object id C function is fetching an object from a memory space that it shouldn't be?
