Hi Jamie,
Three time points should not be a memory problem. You can try to run this on
linux. Or you can get a new binary for the mac from our development version
with several improvements and fixes including a memory leak that might have
caused this. Let me know (you may want to rerun all your bases with the new
version then to avoid introducing a bias, it uses cubic interpolation and
should produce better results).
