Hi Brian,
It might have too many groups -- I'm not sure. How big is pretty big,
also? >2 gigs? >4 gigs?
I'd suggest moving it out of the way for now and continuing on.
Stephen, if you're listening, is it possible that the .yt file has had
a ridiculous number of HDF5 groups made, which is confusing and
overflowing h5py?

Matt,
The sim is a 1024^3 box. They .yt file is pretty big, as it was created earlier during a halo finding and merger tree building job, but it's only creating 18 projections per dump. This error came about before even the first projection was created and saved, so there are none in there.
Thanks, Brian

Hi Brian,
Can you tell us a little bit about the .yt file (or whichever file it's saving to)? Is it humongous, or does it have a ridiculous number of objects in it already? How many projections have you saved to it? How big is the sim?
