[jira] [Commented] (CASSANDRA-13362) Cassandra 2.1.15 main thread
stuck in logback stack trace upon joining existing cluster
[ https://issues.apache.org/jira/browse/CASSANDRA-13362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16172779#comment-16172779 ]
Thomas Steinmaurer commented on CASSANDRA-13362:
------------------------------------------------
Sorry for not replying earlier. At the end, it was an error on our side, introducing some kind of locking issue on STDOUT for the Cassandra process. I think this issue can be closed.
