To me it doesn't look like unloading a Solr Core frees the memory that the core has used. Is this how it should be?
I have a big index with 50 million documents. After loading a core it takes 300 MB RAM. After a query with a couple of sort fields Solr takes about 8 GB RAM. Then I unload (CoreAdminRequest.unloadCore) the core. The core is not shown in /solr/ anymore. Solr still takes 8 GB RAM. Creating new cores is super slow because I have hardly any memory left. Do I need to free the memory explicitly somehow? /Tim
