Heap usage

I am currently printing the heap report when free memory is below 10k or above 50k to see where the memory is used. As you can see, the big difference between the 2 screenshots is "process 0x3ffd1018", which pretty much accounts for the 40k. Is there any way of knowing more about what that process is doing?

I guess you are not running Jaguar on this.

Copy code
print_objects "myprog" --gcerikcorry
