      will.shulman shared a sporadic exception on getMore commands issued by the Ruby driver in the #ruby Slack channel earlier today:

      2019-10-22T08:30:59.786-0700 I ACCESS   [conn145582] TypeMismatch: Field 'getMore' must be of type long in: { getMore: 2105132016...

      The cursor ID happened to be smaller than INT32_MAX and the driver encoded it as a 32-bit integer type instead of 64-bit, which triggered some strict validation error on the server side. The find/getMore/killCursors spec does state that those commands use 64-bit integers for cursor IDs, so this would appear to just be an instance of the Ruby driver not fully complying with that spec.
