[yt-users] clump finder crash

[Elizabeth Tasker]

I should maybe add that I'm running this on a disk object and I was previously using connected sets on its own without the clump find wrapper, and that was no problem.

I think that means that either it's the periodic nature that's an issue or it's a memory issue because the number of iterations clump find is doing?
