[jira] [Commented] (CASSANDRA-7286) Exception: NPE

["Julien Anguenot (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14085049#comment-14085049 ] 

Julien Anguenot commented on CASSANDRA-7286:
--------------------------------------------

Michael, the NPE is happening on production cluster nodes and it is very hard to tie to a particular app level operation.

I will enable debug logs on couple of nodes and let you know when an NPE occurred. It is happening every couple of days on each node.
