Failed to set GID PANIC

[Virginia Galvin]

smb.log  has  several entries like this:

lib/util_sec.c assert_gid(72)
failed to set gid priveleges to (-1,-2)
now set to (0,0) uid (0,0)
lilb/util.c: smb_panic (113()
PANIC failed to set gid



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.

smb.log says

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
