you never answered yoniks question about wether you see any "Closing Searcher" messagges in your log, also it's useful to know what you see in the CORE section when you look at stats.jsp ... typically the "main" searcher is listed there twice, but during warming you'll see the old searcher as well ... if older searchers aren't getting closed for some reason, they should be listed there. i'd start by confirming/ruling out hte old searchers before speculating about the indexwriter or other problems. : > On a quiet system, you should see the original searcher closed right : > after the new searcher is registered. : > : > Example: : > Mar 11, 2009 2:22:25 PM org.apache.solr.core.SolrCore registerSearcher : > INFO: [] Registered new searcher searc...@1f1cbf6 main : > Mar 11, 2009 2:22:25 PM org.apache.solr.search.SolrIndexSearcher close : > INFO: Closing searc...@acdd02 main -Hoss
