> OOM in chaos testing scenario:
> *Chaos configuration:*
> * Kill a random pod in the cluster.
> * Wait until the pod is ready, node joins physical and logical topology.
> * Take a pause for 3 minutes.
> * Repeat from step #1.
> *Steps to reproduce:*
> * Start the replication from a huge amount of data
> * Start the chaos script that will work for the whole duration of replication.
> * Monitor the number of records in the tables.
> Heapdump shows that the problem is in the
> {{PartitionReplicaListener#txCleanupReadyFutures}} map that holds ~600 mb in
> several {{PartitionReplicaListener}}.
