Subject [jira] [Commented] (CONNECTORS-1070) Agents thread exception loop
Date Thu, 09 Oct 2014 13:19:33 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14165115#comment-14165115

Karl Wright commented on CONNECTORS-1070:
-----------------------------------------

Hi Kamil,

I don't know at what point the combined service fails to come up, but I suspect that it does
some initialization before it errors out.

Can you please remove it from tomcat and try again?
