Philo Yang created CASSANDRA-8477: ------------------------------------- Summary: CMS GC can not recycle objects Key: CASSANDRA-8477 URL: https://issues.apache.org/jira/browse/CASSANDRA-8477 Project: Cassandra Issue Type: Bug Components: Core Environment: 2.1.1 or 2.1.2-SNAPSHOT(after CASSANDRA-8459 resolved) Reporter: Philo Yang Attachments: cassandra.yaml, histo.txt, jstack.txt, system.log
I have a trouble in my cluster that CMS full gc can not reduce the size of old gen. Days ago I post this problem to the maillist, people think it will be solved by tuning the gc setting, however it doesn't work for me. Then I saw a similar bug in CASSANDRA-8447, but [~benedict] think it is not related. With the jstack on https://gist.github.com/yangzhe1991/755ea2a10520be1fe59a, [~benedict] find a bug and resolved it in CASSANDRA-8459. So I build a latest version on 2.1 branch and run the SNAPSHOT version on the nodes with gc trouble. However, there is still the gc issue. So I think opening a new tick and post more information is a good idea. Thanks for helping me. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
