Bob Barrett commented on KAFKA-8325:
------------------------------------
[~mbarbon] Would you be able to upload producer logs from around the time this
error was raised? This error is caused when the producer tries to deallocate a
batch that has already been deallocated. There are multiple reasons a batch
would be removed; the stack trace in this case shows the producer attempting to
remove a batch that has expired. Additional logs might tell us what actually
removed the batch before this call was made. If you don't have logs, are you
aware of any interesting producer event around the time of this error, such an
aborted transaction or a request timeout?
> Remove from the incomplete set failed. This should be impossible
