I can reproduce some kind of searcher leak issue here, even w/o SolrCloud, and I've opened https://issues.apache.org/jira/browse/SOLR-3392 -Yonik lucenerevolution.com - Lucene/Solr Open Source Search Conference. Boston May 7-10
Re: # open files with SolrCloud
Yonik, This same issue we have on our production with Solr 4 Trunk build running on Cent OS, JDK 6 64-bit I have reported java.io.IOException: Map failed and Too many open files issue, i seems their is a search leak in Solr which is not closing them and file being kept open. It would be great help if we can resolve this issue, I was going to try latest build but it seems this issue is not resolved yet http://lucene.472066.n3.nabble.com/Large-Index-and-OutOfMemoryError-Map-failed-td3872891.html On Sat, Apr 21, 2012 at 11:57 AM, Yonik Seeley yo...@lucidimagination.comwrote: I can reproduce some kind of searcher leak issue here, even w/o SolrCloud, and I've opened https://issues.apache.org/jira/browse/SOLR-3392 -Yonik lucenerevolution.com - Lucene/Solr Open Source Search Conference.

forgot to mention we are not using Solr Cloud yet but we use Lucene NRT feature, This issue is happening WITHOUT Solr Cloud On Sat, Apr 21, 2012 at 8:14 PM, Gopal Patwa gopalpa...@gmail.com wrote: Yonik, This same issue we have on our production with Solr 4 Trunk build running on Cent OS, JDK 6 64-bit I have reported java.io.IOException: Map failed and Too many open files issue, i seems their is a search leak in Solr which is not closing them and file being kept open.
