Subject [jira] [Commented] (CONNECTORS-1581) [Set priority thread] Error tossed: null during startup
Date Fri, 08 Feb 2019 14:56:00 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16763667#comment-16763667
] 

Karl Wright commented on CONNECTORS-1581:
-----------------------------------------

I am pretty concerned that the database layer is fundamentally not working right.  The fact
that the set priority thread recovers argues that there is a database failure that silently
resolves.  This is bizarre.

If the thread actually finally starts, then you should be good to go other than the concerns
expressed above.
