Welcome to the list.
As first step, you might -stdes- your data set and check the maximum exit
time (or just -stset- without any parameters). Alternatively, -codebook- your
time-to-event variable. One has to be suspicious that lurking somewhere in
your data is a t=40 or thereabouts. I don't think tinkering with the entry or
origin will illuminate the problem.
