[Samba] A lot of zombie processes on Debian 9

[L.P.H. van Belle]

Can you try with this systemd unit file. 
Restarting does not close all prosesses with that one. 
( you need : ExecReload=/bin/kill -HUP $MAINPID ) 
Jessie used probely sysv and not systemd, which should explain why there are so many zombies. 


[Unit]
Description=Samba AD Daemon
Documentation=man:samba(8) man:samba(7) man:smb.conf(5)
After=network.target

[Service]
Type=notify
NotifyAccess=all
PIDFile=/server/samba/bin/var/run/samba.pid
ExecStart=/server/samba/bin/sbin/samba
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target
