Markus Jelsma created SOLR-10420: ------------------------------------ Summary: Solr 6.x leaking one SolrZkClient instance per second Key: SOLR-10420 URL: https://issues.apache.org/jira/browse/SOLR-10420 Project: Solr Issue Type: Bug Security Level: Public (Default Security Level. Issues are Public) Affects Versions: 6.4.2, 6.5 Reporter: Markus Jelsma Fix For: master (7.0), branch_6x
One of our nodes became berzerk after a restart, Solr went completely nuts! So i opened VisualVM to keep an eye on it and spotted a different problem that occurs in all our Solr 6.4.2 and 6.5.0 nodes. It appears Solr is leaking one SolrZkClient instance per second via DistributedQueue$ChildWatcher. That one per second is quite accurate for all nodes, there are about the same amount of instances as there are seconds since Solr started. I know VisualVM's instance count includes objects-to-be-collected, the instance count does not drop after a forced garbed collection round. It doesn't matter how many cores or collections the nodes carry or how heavy traffic is. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
