Kakfa running with high Memory usage

Products

• DX Operational Intelligence

Issue/Introduction

We have 3 replicas of Kafka, all set with 36Gb. These 3 replicas are running with 95% memory usage, is his can be a problem?

Environment

DX O2 On prem any release.
DX O2 SaaS

Resolution

You must pay attention if Kafka is restarting. Normally, this behavior will happen if memory reaches 100% usage. If so, then we may need to investigate by collecting Kafka logs.
Considering the proposed scenario, this is a normal behavior for Kafka and this architecture, even SaaS runs with the same memory consumption.
