Question for the team, currently I do return if the ack is waiting for a reply. Currently we do not respond with any errors in 2.10.x so that will need to wait for 2.11 (@jnmoyne) but should we not return and let the ack timeout instead? @ripienaar interested in your thoughts here. |
We also no longer register pre-acks when we detect this from a consumer snapshot since we properly handle this now and this could lead to excessive memory usage. Signed-off-by: Derek Collison <derek@nats.io>

ok after thinking I believe we should timeout on an AckSync and err when we hit 2.11. I force pushed the change to the code and the test. |

I agree that it should error out in 2.11 (e.g. especially if at the same time we start erroring out also in case it's the message is already ack'd). |

Detect if we receive an ack past our last stream sequence.
We also no longer register pre-acks when we detect this from a consumer snapshot since we properly handle this now and this could lead to excessive memory usage.
