Ishan Chattopadhyaya commented on SOLR-10420: --------------------------------------------- Nothing changed in that code in the last few releases. Do you know if this worked fine in a prior 6x release? FYI, [~dragonsinh] and [~shalinmangar] <-- experts in that code. > 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: 6.5, 6.4.2 > 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
