After kafka is used for a period of time, the memory will continue to rise until it runs out of memory.

However, in fact, Kafka has only 3 low-frequency consumers working continuously, and the available memory allocated to Kafka is 4G.

The following are the startup parameters of kafka：

docker run  -d --name kafka --restart=always \
  --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 \
  -p 9092:9092 \
  -e KAFKA_HEAP_OPTS=-Xmx4G \
  -e KAFKA_LOG_RETENTION_HOURS=1 \
  -e KAFKA_LOG_CLEANUP_POLICY=delete \
  -e KAFKA_LOG_RETENTION_BYTES=1073741824 \
  -e KAFKA_LOG_SEGMENT_BYTES=268435456 \
  -e KAFKA_LOG_RETENTION_MS=300000 \
  -e KAFKA_BROKER_ID=0 \
  -e KAFKA_ZOOKEEPER_CONNECT=127.0.0.1:2181 \
  -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://127.0.0.1:9092 \
  -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 -t wurstmeister/kafka

The running version is：kafka_2.13-2.8.1

How to troubleshoot or solve this situation? thank you very much!
