There had been no changes to the call of the %restart_on_update macro
from the %postun script of the main samba package since four years.
Also I've not seen any complain in this regard.
And after I messed up a bit once in the past the guilde line is to keep
the scripts as simple as possible.

Due to the nature of how the %restart_on_update is constructed it should
be(tm) impossible to stop a service without starting it again. The
implementation of the %restart_on_update utilizes the try-restart case
of the init scripts.
From now anything is guessing: The process got the TERM signal but
failed to finish. As the port was still in use the (re)start failed.
 try-restart(LSB) is equivalent to condrestart(RedHatish systems).
