[Samba] AD DC eventually not browsable without restart

[Ricky Nance]

I wonder if your hitting the /run/lock fill up that another user reported
on a week or two ago (they are using ubuntu). I think the solution was to
make that tmpfs partition bigger (like 50 mb instead of 5 mb). next time it
is unresponsive check and see what the output of 'df -h' is.
