Erick Erickson resolved SOLR-11910.
-----------------------------------
    Resolution: Not A Problem

Please raise this question on the user's list at solr-user@lucene.apache.org, see: (http://lucene.apache.org/solr/community.html#mailing-lists-irc) there are a _lot_ more people watching that list who may be able to help.

 

If it's determined that this really is a code issue in Solr and not a configuration/usage problem, we can raise a new JIRA or reopen this one.

You're probably seeing this, and if so it's entirely normal behavior: [http://blog.thetaphi.de/2012/07/use-lucenes-mmapdirectory-on-64bit.html]

> We are using 14 cores in solr with a machine that had 2 cores and 15gb ram, JVM HEAD setted to 4gb. Solr are consuming physical memory until it's over and don't release them. I've searched in foruns and issues and found a try to change NMapDirectory to NIOFSDirectory but not works. Is it possible to resolve?
