I am running solr 4.0 in a cloud. We have close to 100Mdocuments. The data is from a single DB table. I use dih. Our solrCloud has 3 zookeepers, one tomcat, 2 solr instances in same tomcat. We have 8 GB Ram.
After indexing 14M, my indexing fails witht the below exception. solr org.apache.lucene.index.MergePolicy$MergeException: java.lang.OutOfMemoryError: GC overhead limit exceeded I tried increasing the GC value to the App server -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=80 But after giving the command, my indexing went drastically down. Its was indexing only 15k documents for 20 minutes. Earlier it was 300k for 20 min. Any suggestions ?
