One of my Solr Nodes at SolrCloud (4.2.1) was down for a long time. I restarted Solr and after recovery its Physical Memory usage is 99.5% and does not decrease. Thats why I asked that question (I don't know is it usual that Physical Memory did not decreased for 3 days. Why my CentOS 6.4 does not drop caches after a time later and why recovery resulted with such a high Physical Memory usage.)
