Solr stopped with Error opening new searcher at org.apache.solr.core

Question

Yesterday suddenly our solr server got stopped with following exception

org.apache.solr.common.SolrException: Error opening new searcher at org.apache.solr.core.SolrCore.openNewSearcher(SolrCore.java:1438) at org.apache.solr.core.SolrCore.getSearcher(SolrCore.java:1550) at org.apache.solr.core.SolrCore.getSearcher(SolrCore.java:1319) at org.apache.solr.update.DirectUpdateHandler2.commit(DirectUpdateHandler2.java:574) at org.apache.solr.update.processor.RunUpdateProcessor.processCommit(RunUpdateProcessorFactory.java:95) at org.apache.solr.update.processor.UpdateRequestProcessor.processCommit(UpdateRequestProcessor.java:64) at org.apache.solr.update.processor.DistributedUpdateProcessor.processCommit(DistributedUpdateProcessor.java:1147) at org.apache.solr.update.processor.LogUpdateProcessor.processCommit(LogUpdateProcessorFactory.java:157) at org.apache.solr.handler.loader.XMLLoader.processUpdate(XMLLoader.java:266) at org.apache.solr.handler.loader.XMLLoader.load(XMLLoader.java:173) at org.apache.solr.handler.UpdateRequestHandler$1.load(UpdateRequestHandler.java:92)

Caused by: java.io.IOException: Map failed at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:889) at org.apache.lucene.store.MMapDirectory.map(MMapDirectory.java:283) at org.apache.lucene.store.MMapDirectory$MMapIndexInput.

But at that time we have lot of memory left in that server. Any guess?

Assuming its a linux system you can try ulimit -v unlimited

You will get answers much faster if you include more information, like the version of your software (in this case solr version), OS Name and version, Java version etc.
