This with version 4.17.5. OS is redhat 9.2.
We have not tried the latest, but fd_close() function has not changed, and is still skipping fsp_set_fd(fsp, -1); on stat() call error.

What version of Samba is this ?
On what OS ?
If it isn't a very recent version of Samba, have you tried upgrading Samba, just in case it has already been fixed.
