It depends how you are running solr. You basically want to make sure that when the JVM is started up with the java command, that it gets some additional arguments [1]. So for example if you are running solr using jetty you would: java -verbose:gc -Xloggc:solr_gc.log -jar start.jar And then poke around in the log looking for garbage collection events that take as long as the pauses you are seeing in your app. I think there are tools that will help you analyze the log files if you need them. If there is a correlation you'll probably want to tune your solr memory usage with -xMx and -xMs. Hope this helps. //Ed [1] http://java.sun.com/javase/7/docs/technotes/tools/windows/java.html
