[Samba] smbcontrol reload & close-share not working like previous version

I just upgrade my kernel, smbd and changed my smb.conf. (4.14.12-1-Arch" to
"4.14.19-1-lts") "samba 4.7.4-1"
But now, "reload smbd" and "close-share" can not drop connected users to
share. Because of that I have to restart smbd service for destroy a share
right now.
But it was working previous version and I don't know what is wrong right
now. As you know, restarting SMBD affects other shares. This is dirty way
to an easy job.

When I try to destroy a share I follow these steps:

1- Edit smb.conf "delete include line"
2- Delete samba share conf (what is included)
3- smbcontrol smbd close-share
4- smbcontrol all reload-config or "systemctl reload smbd"
5- zfs destroy dataset

This steps not working anymore because user still won't disconnect share
until service restart.
When I close a share I need to take out users from the share because when
they still use the share I'm getting "busy" error when I try to destroy

Any advice please?
