My logs are getting spammed with "Unable to retrieve filters from /rest/activity-stream/1.0/config?local=true ... org.codehaus.jackson.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')" messages from the StreamsCompletionService.
We don't have any custom things in the activity stream, so I don't even know where to start with this one, but the Activity Stream widget on the dashboards is really slow and then times out with "One or more activity sources were slow to respond and are not included. You can try again with a longer timeout."
It says this even though it's only supposed to be getting stuff from Jira and Confluence, and displays updates from both, so I don't know what other "activity sources" it is referring to.
