Dear Tom,
have you tried to estimate it with clogit? Does the problem also occur
there? Could give us a little bit more detail about the error message?

Well I don't know but one direction to check is that that is a huge dataset.
So try randomly subsampling down to, say 10% and see if that works. Maybe
you're running into some weird memory or matrix size problem. Usually Stata
would appropriately whine, but who knows.
