Answer 1

Try to increase your memory

Either set the environment variable JAVA_OPTS="-Xms256m -Xmx500m" which means heap start size is 256 MB, max 512 MB. Or edit your catalina.bat or .sh and add this line there.

You have to play around with these values, some weeks ago I had an SOLR indexer job, about 2 GB of data, 700MB heap were required.
