This is just a guess, but what is ReserveCache set to in your config.ini? Or is it set at all? Based on the output above, I don't think you have it set, and with emphatic running, that's bad. On the emphatic page, I suggest setting ReserveCache=48 (under the [Startup] section) so that emphatic has enough memory to run.

Having said that, it's the player app that's crashing, but I think that could be due to emphatic thrashing about in a very small memory space (whatever little bit the player leaves free by default.) Adding ReserveCache will save some room for user apps like emphatic.

I'm not sure this is what's going on, but try it out.
