I'm not aware of any memory leaks in Virgo. There were changes in both the code and some libraries, so it's possible Virgo to have different memory utilization.
If you suspect a memory leak it is worth to periodically take a snapshot of the objects in the heap via some profiler. That's however usually done on test/development system.
The heapdump is OK for a productive system since it will take only 5-6 seconds, and the data can be analyzed offline. Be warned that the heapdump contains all the data in the heap (as one would expect), including a possibly sensitive data (user names, passwords if they are kept in memory and so on).
It's also worth checking if there were any full GCs. If not perhaps the memory has not been freed yet.
Please share any findings on the forum, so this can be of help to other users as well
