samba - May 2001 - core dumps on HP 785-9000 when access from W2K -Why?

I made  samba  on an HP 785-9000 running  hpux 10.2
Running smbd and nmbd on the HP I can access shared
home directory from a W2K Professional

But each time I access the HP home directory from the W2K system
I get a core dump file in the HP home directory.


Core dump does not seem to affect access to the file .
I can  read/write to the HP file from W2K.
Does anyone know Why is this dumping core?
thanks
