---------------------------------------------------------------
Yes. I get something similar. Worked fine for about six runs then got a run
with:
At least one acked message did not appear in the consumed messages.
acked_minus_consumed: set([29073, 29067, 29076, 29070, 29079])
Which i have not seen before (i.e. just a few messages missing).
The five messages were produced at 11:29:19. Interestingly this time
corresponds to the consumer's first notifications that the coordinator is dead
(below). These come a few secs after the second node (of 3) is shutdown.

Yes. I get exactly the same. Worked fine for about six runs then got a run with:
At least one acked message did not appear in the consumed messages.
acked_minus_consumed: set([29073, 29067, 29076, 29070, 29079])

> Gaps in messages delivered by new consumer after Kafka restart
> --------------------------------------------------------------
>
> Key: KAFKA-2891
> URL: https://issues.apache.org/jira/browse/KAFKA-2891
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.9.0.0
> Reporter: Rajini Sivaram
> Priority: Critical
>
> Replication tests when run with the new consumer with SSL/SASL were failing
> very often because messages were not being consumed from some topics after a
> Kafka restart. The fix in KAFKA-2877 has made this a lot better. But I am
> still seeing some failures (less often now) because a small set of messages
> are not received after Kafka restart. This failure looks slightly different
> from the one before the fix for KAFKA-2877 was applied, hence the new defect.
> The test fails because not all acked messages are received by the consumer,
> and the number of messages missing are quite small.
> [~benstopford] Are the upgrade tests working reliably with KAFKA-2877 now?
> Not sure if any of these log entries are important:
