Glad you got the warning out of there. Noticing that the message said "OpenJDK" I am betting you still have OpenJDK 7u25 on the system. I really was serious when I recommended getting the latest Oracle Java that you could on the system. Memory management has seen a lot of improvement since the early Java 7 days. There's nothing wrong with OpenJDK, as long as it's not OpenJDK 6, but overall we do see the best results with the Oracle JVM. If you want to stick with OpenJDK, it would be a very good idea to get the latest v7 or v8 version instead of the old version you've got. 7u25 is over two years old. Java development moves very quickly, which makes that version a lot like ancient history. Part of the reason that my general recommendation is Java 8 is that both Java 6 and Java 7 have reached end of support at Oracle. There will be no more development on those versions. Having said that, note that it's just a recommendation, whether you follow that recommendation is up to you. I found 7u25 to be a very solid release ... but release 60 and later have better memory management. Don't use 7u40, 7u45, 7u51, or 7u55 -- those versions have known bugs that DO affect Lucene/Solr. Thanks, Shawn
