Subject [jira] [Resolved] (LUCENE-4144) OOM when call optimize
Date Thu, 14 Jun 2012 12:49:42 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael McCandless resolved LUCENE-4144.
----------------------------------------

    Resolution: Not A Problem

Please raise this on the java-user@lucene.apache.org list instead.

Also, we've made good reductions in RAM usage since 2.1, so it could be simply upgrading to
the latest (3.6) resolves this.
