I;m curious if you looked at all to the program size, and not the size of the GC ? It may be that a 'native' routine leaks independently of the GC. BTW, that a yes. JVM calls upon many functions/services/libraries to do its bidding. Any one of them may request memory ( from the system pool ) ,

I'm trying to troubleshoot some really bizarre behavior in a recent build of our application. We have changed our memory usage quite a bit, utilizing more caching, etc. Overall performance has unsurprisingly improved and all looked good during QA after we tackled some memory leaks and unbounded c
