Nick, to solve out of memory issue, i think you can make below change: 1) in solrsconfig.xml, reduce ramBufferSizeMB (there are two, change both) 2) in solrsconfig.xml, reduce documentCache value
to solve call commit slow down index issue, i think you can change new search default queyr: in solrsconfig.xml, search for <listener event="newSearcher" class="solr.QuerySenderListener"> change <str name="q">content:*</str> <str name="start">0</str> <str name="rows">10</str> to <str name="q">content:notexist</str> <str name="start">0</str> <str name="rows">10</str> -- View this message in context: http://lucene.472066.n3.nabble.com/SOLR-4-Alpha-Out-Of-Mem-Err-tp3995033p3995695.html Sent from the Solr - User mailing list archive at Nabble.com.
