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

Ricardo Giacomin created KAFKA-14169:
----------------------------------------

             Summary: Memory leak (?) with no activity
                 Key: KAFKA-14169
                 URL: https://issues.apache.org/jira/browse/KAFKA-14169
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 3.2.1
         Environment: AKS, Linux-based Kafka cluster setup
            Reporter: Ricardo Giacomin
         Attachments: image-2022-08-16-11-05-32-227.png, image-2022-08-16-11-07-51-565.png

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?
