I hate to admit but my "IBM architect style" game engine did something really stupid and accumulated lots of redundant sound samples over the life time of the application process. Basically every time when the game activity restarted and resources are loaded, the previously loaded sound samples were still registered and loaded again.
So just for the record: that crash can apparently happen when you try to load too many sound samples (or maybe too many times the same sample over and over again).
