[Samba] Samba AD/DC crashed again, third time in as many months

I had to move forward with my restore process, couldn't wsit any longer for
confirmation on extended ACLs.  As I understand it the version of
samba_backup that Rowland supplied me in January backs up these ACLs as
long as my version of gnutar supports it, and afaik the version of gnutar I
have installed does, so I took a leap of faith and just restarted samba
using the init script I have in /etc/init.d.

After executing *sudo /etc/init.d/samba4 start  *I then issued the
command *sudo
/etc/init.d/samba4 status  *and received the following output:

sudo /etc/init.d/samba4 start
[ ok ] Starting samba4 (via systemctl): samba4.service.

The domain is up again, ACLs appear to have been retained, user accounts
and groups are intact, shared folders are accessible.

I'll be doing an immediate samba_backup and will be taking a hard look at
the hardware behind this ADC.  I'll also probably be spinning up a second
ADC in a VM hosted on another machine in an attempt to make this deployment
more robust, and I'll be moving this ADC implementation to a VM as well.

Thanks again to everyone here who offered advice and support, I appreciate
your time and expertise.

Kind Regards,

JS

PS - if you're ever in Detroit, MI and like Jazz, ping me and I'll take
care of you.
