Hi,
This basically means that besides the biggest objects (objects retaining more heap than a given threshold) there are objects which consume about 5 Gb.
This could mean that you have millions of small objects (possibly of one or more classes), or it could also mean that you have a few (may be hundreds) of pretty big objects (but not big enough to be listed among the biggest).
Have you tried running the leak suspect report? It would try to do some grouping, which could be helpful. See this blog for more info:
http://dev.eclipse.org/blogs/memoryanalyzer/2008/05/27/autom ated-heap-dump-analysis-finding-memory-leaks-with-one-click/
If this doesn't help, you can try exploring the dominator tree manually (try also grouping by class there).
It could be at the end that the 5GB are just what the app needs to work properly under the load you have. In this case you can try the top components report, which should give you some hint which are the components using most of the heap and some other details which can be useful.
Let me know if this hints help.
