Ryan P created KAFKA-6893:
-----------------------------
Summary: Processors created after acceptor started which can cause
in a brief refusal to accept connections
Key: KAFKA-6893
URL: https://issues.apache.org/jira/browse/KAFKA-6893
Project: Kafka
Issue Type: Bug
Affects Versions: 1.1.0
Reporter: Ryan P
Assignee: Rajini Sivaram
The acceptor starts before the the processor threads are actually created which
creates a very small window in which connections to the broker will fail. When
the acceptor takes on a new connection an illegal arithmetic exception is
thrown as shown below.
Exception: / by zero
