> URL: https://issues.apache.org/jira/browse/KAFKA-5543
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.11.0.0
> Reporter: Apurva Mehta
> Assignee: Apurva Mehta
> Fix For: 0.11.0.1
>
>
> Reported by [~junrao], we have a small leak where the `LastStableOffsetLag`
> metric is not removed along with the other metrics in the
> `Partition.removeMetrics` method. This could create a leak when partitions
> are reassigned or a topic is deleted.
