ReplicaManager OutOfOrderSequenceException

[Nicolas Carlot <ni...@chronopost.fr.INVALID>]

Hello,

I'm having multiple errors in our kafka cluster server.log regarding a
single topic and a subset of its partitions.

ERROR [ReplicaManager broker=1] Error processing append operation on
partition declaration.amount-to-c50builder-30 (kafka.server.ReplicaManager)
org.apache.kafka.common.errors.OutOfOrderSequenceException: Invalid
sequence number for new epoch: 16244 (request epoch), 2 (seq. number)

Doesn't seem to impact the replication mecanism as all replicas are shown
to be in sync, but there are tons of occurence of this error in the logs.

I wonder why it's happening, and why it's only for this perculiar topic ?
