Subject [jira] [Updated] (CASSANDRA-11374) LEAK DETECTED during repair
Date Wed, 13 Apr 2016 23:06:25 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-11374?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Anubhav Kale updated CASSANDRA-11374:
-------------------------------------
    Attachment: Leak_Logs_2.zip
                Leak_Logs_1.zip

Attached Leak_Logs*.zip that show this error on Cassandra 2.1.13 while bootstrapping. This
is a consistent repro for us. Our node size is ~300 GB.

The process stays up after the leak message, but doesn't do much and the node is eventually
removed from gossip (thus doesn't show up in gossipinfo / status on other nodes).

The only workaround seems to be letting the node boot with auto_bootstrap=false and then do
a nodetool rebuild.
