Because your operating system kernel returns a "Resource temporarily
unavailable" error.
It is also posible that it returns "Resource temporarily unavailable"
because Postfix has used up all the available sockets.
In that case, reduce Postfix process limits (main.cf:default_process_limit
and in master.cf) by 2x and do "postfix reload" until the error goes away.
