Has this to do with KAFKA-1461?
Can you see which thread is taking a lot of cpu? Some jconsole plugin can
get that information.

Hi Jay,
Good to hear from you. I met you at the kafka meetup at linkedin.
- No, I am running kafka_2.11-0.8.2.1
Are there any logs/ any info that I can provide that will help you
understand what could be the issue?
Thanks,
Anuja

This sounds a lot like a bug we fixed in 0.8.2.0, no chance you are running
that pre-release version is there?

There are no messages being sent or received. The system is idle.
however, there seems to be some GC going on in the kafka broker and some
socket reads and writes. It is using approx 500MB of memory.

Hi Otis,
How do I check garbage collection on kafka broker?

Hi,
I am using Kafka 0.8.2.1.
We have 1 zookeeper, 3 kafka brokers.
We have 9 topics, out of which 1 topic has 18 partitions, while another has 12
partitions. All other topics have 1 partition each.
We see that idle kafka brokers (not carrying any message) are using more than
50% of CPU. See to
