[KAFKA-14169] Memory leak (?) with no activity

Description

I have deployed a 3-node Kafka cluster (see setup below).

I didn't touch the cluster since installation (did not create any topic or run any consumer/producer) and yet the memory usage is increasing, as displayed by the last 48 hours chart below.

 

Sounds like a memory leak??? The strange (increasing in steps) behaviour suggests some periodic jobs running but I didn't configure any.

Any hints?
