Which version of Java are you using? Please try the standard tricks: Do a fresh checkout of the Solr trunk. Do 'ant clean dist' and use the newly built war & latest lucene libraries. Try changing the JVM startup parameters which control how incremental compilation works: -server and others. Also try changing the garbage collection algorithms.
