Nothing you say sounds problematic to me and you have covered the usual culprits overlapping searchers, faceting and filterCache. Is it possible for you to share the solr.log around the two times that memory usage peaked? 2017-11-30 17:00-19:00 and 2017-12-01 08:00-12:00. If you cannot share, please check if you have excessive traffic around that time or if there is a lot of UnInverting going on (triggered by faceting on non.DocValues String fields). I know your post implies that you have already done so, so this is more of a sanity check. - Toke Eskildsen
