Idle cluster increasingly consumes CPU resources ------------------------------------------------
Key: ZOOKEEPER-883 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-883 Project: Zookeeper Issue Type: Bug Components: server Reporter: Lars George Monitoring the ZooKeeper nodes by polling the various ports using Nagios' open port checks seems to cause a substantial raise of CPU being used by the ZooKeeper daemons. Over the course of a week an idle cluster grew from a baseline 2% to >10% CPU usage. Attached is a stack dump and logs showing the occupied threads. At the end the daemon starts failing on "too many open files" errors as all handles are used up. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
