sjohnson540 we discussed that backport is high-risk. I'm currently researching the value of the backport to 3.6 to assess it against the risk. Can you give us an idea of the impact of having to wait till 4.0 for the fix for you? Feel free to e-mail me at asya at mongodb.com if you want to discuss things you'd rather not mention publicly. |

asya just curious – when is the next triage meeting planned for? |

Yes they are all a part of the same sharded cluster. Most replica sets have one or two collections on them. |

sjohnson540 we are going to discuss the backport to 3.6 at our next triage meeting. We originally decided not to backport it because of complexity of the change but will reconsider it now. Just to confirm, you observe this happening on a sharded collection (you mention 80 replica sets but not if they are part of a sharded cluster)? |

@NicholasZolnierz I was hoping to get an update on this. Is there any possibility of it being backported to 3.6. It breaks the functionality of Change Streams for our cluster. We are currently running ~80 replica sets in production. As such we cannot afford to jump major versions for a bug fix, but if it was backported we could have it rolled out very soon, and would be happy to share our experience running changestreams on large deployments. |

Hello! I have ran into this issue with our change streams in our staging environment in preparation to deploy to production. Is this fix going to be backported to 3.6.(6?) or will it only be released in 4.0? |

Thanks greg.mckeon, that's correct this was originally scoped for 4.0. |

nicholas.zolnierz I'm under the impression this is intended for 4.0, so I've requested the backport. shane.harvey so he's aware this may break drivers testing against 4.0 once we backport. |

nicholas.zolnierz does this need to get into 4.0? CC greg.mckeon. |
