OK - I have spent a few weeks trying to track down a memory leak that is in our application. We see the leak in that the yourkit profiler shows an increasing trend in telemetry. BUT, in tyring to track it down, all the GC roots of the largest objects are coming from things like JDBC caches, el.ExpressionEvaluatorImpl cache, WebAppClassLoader, and other Tomcat managed caches/pools.
How do I know what memory is expected to be retained by Tomcat outside of my application classes???? There seems to be caches / pools / classloaders as almost every GC root. Is there some list out there that defines valid Catalina GC roots for a running webapplication?? If not, Then how does one know whether you are looking at a leak or some cache/pool that is managed by something else, and assumabley works correctly? Also, if we have around 200 static classes, should we increase PermGen or Heap size? Is there anyone out there who could help on this issue. Fee for service is possible.
