The default heap size on Solr 5.x is 512MB. This is extremely small, it doesn't take much index data for this amount of memory to be exceeded. Another message you sent to the list mentions "-m 1g" when starting Solr ... even a gigabyte of RAM might be very small, depending on exactly how Solr is configured, what is indexed into Solr, and how it is being queried. Unless you can take steps to make Solr use less memory, you're going to need to increase the max heap. Thanks, Shawn
