Peter,

In my phpesp install (1.8), I have a survey that has 588 responses,
and the survey itself has only 17 questions though.  I wonder if
anyone else have ever had a survey of your size that they have tried
to export?  It very well sounds like it could be timing out php just
because of the amount of time it could take the script to run.

Have you tried the "Save to server" option?  What does that result
produce?
