Well, that's really strange.We have a lot of servlets users on NT and no one
report that problem. Did you get any trace by launching Jigsaw with the
-trace option? did you see something special in the errlog file?
I really don't know what's happen but, IMHO it's a problem with your
configuration (where? that is the question)

Is there someone on the list who had the same problem on NT?

Regards, Benoit.
