I ran out of dynamic memory. I've free'd up enough but how can I know.

Hello.
I've got a teensy3.2 flashing a about 2000 ws2811 lights using fastled/octows2811 libraries.

I added another tree of lights today and my program froze.

I had some multi-byte data structures for each led that I was able to trim down from int to uint8_t that probably puts me well in the clear but it has me wondering... short of stepping through my program with a calculator how can I check dynamic memory that will be used at runtime.

Thanks.
