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.
