We have a pretty standard out-of-the-box solr/jetty setup. Using the web UI at /solr/admin/logging, for WARNING or SEVERE we get less logging, but none of CONFIG, FINE or FINEST result in any *more* logging than just at INFO.
Is there another place to look for something that might be controlling that? Maybe a threshold=INFO somewhere? We've been unable to find anything. We're trying to turn up logging because our solr indexing server is hanging at least once a day and we're trying to find out why. It becomes unresponsive and we have to kill -9 it.
