[jira] [Commented] (CONNECTORS-846) Multiprocess-file example: Hang when editing job after job has been running

["Karl Wright (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONNECTORS-846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13852195#comment-13852195 ] 

Karl Wright commented on CONNECTORS-846:
----------------------------------------

Possibilities include:
(a) webapps are not calling poll properly
(b) connectorpool is not able to relinquish connector instances, and so once a process grabs them all they cannot be reallocated
(c) service registration is messed because webapp isn't cleaning up properly.
