You fail to tell us anything whatsoever about your data (except that
the number of observations presumably is at least 3000) and you do not
tell us even the exact command you typed. This is quite contrary to
all the advice given to you in the FAQ and in particular repeated on
the list within the last 24 hours.

-set trace on- will show you where what you think is a problem occurs.
If the resulting log is long you may need to edit it for Statalist.
Otherwise why not liaise with Stata technical support directly? As
above, they will want to know about your dataset.
