Subject [jira] Resolved: (SOLR-2180) Requests to Embedded Solr (often) leave old Searchers open
Date Thu, 21 Oct 2010 17:20:15 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2180?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yonik Seeley resolved SOLR-2180.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 4.0
                   3.1
                   1.4.2

I packported to 3.x and 1.4.x

It's unclear exactly what would have triggered this bug... the SearchHandler.handleRequest
normally catches exceptions and returns normally, so a normal query exception wouldn't have.
 I'm sure there were some ways though.

> SolrEmbeddedServer.request() fails to call SolrQueryRequest.close() at the very end of
a successful request. This (in some situations) causes EmbeddedSolr to leave old Searchers
open until the Solr core stops (core unload, the JVM restarts). This leaves old Solr and Lucene
caches in place, which causes a memory leak.
> A fix for this was committed on the trunk on Sunday, Oct/15/2010. 
> [Revision r1023599  to SolrEmbeddedServer|http://svn.apache.org/viewvc/lucene/dev/trunk/solr/src/webapp/src/org/apache/solr/client/solrj/embedded/EmbeddedSolrServer.java?diff_format=h&revision=1023599&view=markup]
> This should be backported, or the problem checked for, in 1.4.2 and 3.1.
