Summary: Zookeeper client leaks file descriptor in case of UnknownHostException Key: ZOOKEEPER-4650 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4650 Project: ZooKeeper Issue Type: Bug Components: java client Affects Versions: 3.7.1, 3.4.14 Reporter: Rushabh Shah Attachments: Screen Shot 2022-12-13 at 4.30.34 PM.png Zookeeper client is causing the file descriptor leak when it is unable to properly reach the destination. In this case, the DNS lookup fails but still leaves an unbounded TCP socket. A colleague took a heap dump of the application. Saw 17400 sun.nio.ch.SocketChannelImpl object reachable from root and the number matched the open file descriptors on the host. !Screen Shot 2022-12-13 at 4.30.34 PM.png! More analysis from the heap dump in the comment. -- This message was sent by Atlassian Jira (v8.20.10#820010)
