Both longpoll or continuous seem to trigger the behavior. Exception above in couch_event_listener_mfa:handle_event comes from https://github.com/apache/couchdb-couch-event/blob/master/src/couch_event_listener_mfa.erl#L91 which, in turn comes from fabric_db_update_listener handle_db_event returning \{stop, St\} in: https://github.com/apache/couchdb-fabric/blob/master/src/fabric_db_update_listener.erl#L87 It seems couch_event_listerner_mfa:handle_event doesn’t handle \{stop, St\} only, \{ok, NewState\} or just stop or it raises an exception. I tried to replace \{stop, St\} with \{ok, St\} and then with stop. But in both cases change feeds never stopped. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
