Postfix and Mailscanner not working

[Gioia Bastioni]

I guys,

I've a bog problem on my mail server  running postfix 2.0.15 and Mailscanner
2.24.5 on a Slack 9.1
it has been working for a couple of days, and now it's no longer working, I
cant'see ANYTHING on my Maillog, it is all frozen from sunday at 16.56 ..
I can send messages, I have no error shown or logged, but at the end I can't
receive anything ..!!
What I found out is that Mailscanner is not running, so it can't send out
the messagges sent ..
doing a ps-aux here's what I get :
