There doesn't seem to be anything there that will give you your
problem, there are lots and lots of default settings and you really
should be using the default 'tdbsam' passdb backend.

Do you have any Apple computers or phones ?

When Samba starts it will start several processes and when something
connects to a share, smbd will fork into another process to deal with
this. It sounds like this is your problem, something is connecting to
Samba on a regular basis and you need to find out where this connection
is coming from. It could be that one of your Windows machines is
infected.
