-----------------------------------
Summary: Kafka server threads die due to OOME during long running
test
Key: KAFKA-664
URL: https://issues.apache.org/jira/browse/KAFKA-664
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8
Reporter: Neha Narkhede
Priority: Blocker
Fix For: 0.8
I set up a Kafka cluster with 5 brokers (JVM memory 512M) and set up a long
running producer process that sends data to 100s of partitions continuously for
~15 hours. After ~4 hours of operation, few server threads (acceptor and
processor) exited due to OOME -

It seems like it runs out of memory while trying to read the producer request,
but its unclear so far.
