Message: SERVER-28787 Invariant failure with QueryOption_AwaitData
Branch: v3.2

Comment by Nicholas Zolnierz [ 19/Apr/17 ]

This issue is isolated to version 3.2 and was fixed in version 3.3.6 as part of the server ticket SERVER-24045. Fix will be targeted for 3.2 branch only instead of a full backport of SERVER-24045.

Thanks for your report aaron_french, this ticket has been sent to the query team for investigation.
