[jira] [Commented] (CASSANDRA-8851) Uncaught exception on thread
Thread[SharedPool-Worker-16,5,main] after upgrade to 2.1.3
[ https://issues.apache.org/jira/browse/CASSANDRA-8851?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14334226#comment-14334226 ]
Benedict commented on CASSANDRA-8851:
-------------------------------------
There are many improvements in 2.1.4 that will likely help here, and should also help us diagnose by printing more helpful info. If you could try running with the current branch posted against CASSANDRA-8832, we may get some more useful information to work with.
