If I understand the Exim design well, there is one master process (in
your listing the PID 1243). For each incoming connection and each queue
run/delivery the master forks a new child. The parent-child relation is
better visible if you use „ps axf“ or „pstree“.
To get an overview about only running Exim processes you might use
„exiwhat“.

The init script just shuts down the master process, the childs will die
as soon as they've finished their job (or as soon as the machine goes
down or you kill them one by one).

Hm. I see the same exception here. So I do not have any good idea about
this.

About the „sudo“ - no, shouldn't be a mistake, as Exim may start as root
and changes it's EUID to something less dangerous as soon as possible.
