Samba4 and memory consumption - needing frequent kills

[Ricky Nance]

I can confirm this memory leak, with the info found here...
http://paste.ubuntu.com/1136864.
I know its not a remedy to the issue, but a cron job like the following
seemed to make my setup run much smoother...

25 5 * * * /etc/init.d/samba4 stop
30 5 * * * /etc/init.d/samba4 start
