The default configuration for Garbage Collector is still using what was recommended by Alfresco docs when the Solr process used to run in the same JVM as Alfresco (-XX:+UseConcMarkSweepGC -XX:+UseParNewGC)
Nowadays, there are better alternatives, and I am using (tks @afaust for the tip) "-XX:+UseG1GC -XX:+UseStringDeduplication"
I have been using this for all my installations without any problem.
