[jira] [Commented] (CONNECTORS-1070) Agents thread exception loop
[ https://issues.apache.org/jira/browse/CONNECTORS-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14165054#comment-14165054 ]
Karl Wright commented on CONNECTORS-1070:
-----------------------------------------
Hi Kamil,
What model are you using here? Zookeeper or file system?
Is it possible that your first agents process has not finished shutting down before you try to start it again?
In any case, I suggest you try upgrading to MCF 1.7.1, since fixes were made in this area.
Thanks!
