Subject [jira] Commented: (SOLR-2180) Requests to Embedded Solr (often) leave old Searchers open
Date Thu, 21 Oct 2010 15:58:18 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2180?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12923491#action_12923491

Yonik Seeley commented on SOLR-2180:
------------------------------------

My reading of it was that it was only on an exception would the request not be closed (which
is still a serious bug though).
I was cranking on tests and overlooked that this change had a broader impact.

> 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.
