Subject [jira] [Updated] (CASSANDRA-9117) LEAK DETECTED during repair
Date Fri, 03 Apr 2015 22:03:52 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-9117?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tyler Hobbs updated CASSANDRA-9117:
-----------------------------------
    Attachment: node2.log.gz

Hmm, it looks like this may not be specific to repair.  I'm attaching node2.log which shows
a very similar problem during startup.  This is reproducible for me with the {{pushed_notifications_test.py:TestPushedNotifications.restart_node_test}}
dtest.
