-------------------------------------------
Summary: NioCnxnFactory new code opens selectors but never closes
them
Key: ZOOKEEPER-1620
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1620
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.5.0
Reporter: Alexander Shraer
New code (committed in ZK-1504) opens selectors but doesn't close them.
Specifically AbstractSelectThread in its constructor does
this.selector = Selector.open();
But possibly also elsewhere. Tests fail for me with the following message:
java.io.IOException: Too many open files
