Hi All, I encountered once kafka OOM, then I add a monitor to monitor Heap Memory of Kafka.
here is a current status, I set kafka heap max is 96G. you can see it changes significant. so anyone can help to point out where the problem is? thanks in advance. kafka version: 1.0.0 VM parameters: -Xmx96G -Xms96G -XX:+UseG1GC -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35 -XX:+ExplicitGCInvokesConcurrent -Djava.awt.headless=true -Xloggc:/home/ec2-user/kafka_2.11-1.0.0/bin/../logs/kafkaServer-gc.log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M some configuration: max.message.bytes=104857600 replica.fetch.max.bytes=104857600 max.request.size=104857600 fetch.message.max.bytes=104857600 [image: image.png] [image: image.png]
