There is the sgc collector and there is the --enable-backtrace option to the 3m (default) collector. They can require some work to use, tho. They give you more information from dump-memory-stats, I believe (not sure exactly the status of sgc, tho).
Do you find tactical (collect-garbage) calls to actually help?
