Patrick Hunt resolved ZOOKEEPER-883. ------------------------------------ Resolution: Implemented Sounds like this was resolved with ZOOKEEPER-880. Please reopen if it happens again. Thanks Lars. > 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 > Affects Versions: 3.3.1 > Reporter: Lars George > Attachments: Archive.zip > > > 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 was sent by Atlassian JIRA (v6.1#6144)
