Charles, I have tuned the heap size based on what is ideal during peak hours. The problem is that off-hours usage is very different, and leads to these very long full GCs.
Does it sound like an application problem? I have not done any analysis to determine what kind of objects are hanging around. This is a third party application, so there is really not much we can do on that front anyway. Again, unfortunately upgrading is not an option for us at this point.
