Hm.. I'm not quite sure. The problem is - I cannot reproduce it.
But it definitly sounds familiar. Unfortunately I'm not quite sure
about the file size. I will check that as soon as I get the exception
again. _If_ it is the same problem it seems to be around for at least
a week.

Although most people on this list seem to think XSP should be deprecated
I think we should put some more efforts into the XSP machinery. Once
a XSP page is compiled IMHO it should scale as good as hand written
Generator. And although I haven't had a closer look into the XSP
engine yet - this should really be possible.
