[Samba] Samba dfree command not working

[Keram Yasin]

Dear Rowland, Jeremy

I really appreciate your feedback. I just followed your recommendations and
the problem is gone. I still don't know the root cause of the problem. But
I will find it by myself. In the end, I wish you guys a wonderful day. Your
help is priceless. Thank you.

Best regards,
Keram Yasin
