P.S.:

if the new starting process (like the 8442 from your log)
does not come up but fails during a start, a possible reason
is that some files (like a config file or DKIM keys file) is
too strongly protected, so a start as root succeeds, but a
start with reduced privileges fails.

To troubeshoot this, run one instance of amavisd non-daemonized,
e.g.:
  # amavisd foreground
or even:
  # amavisd debug

then request its restart from another concole, e.g.:
  # amavisd reload
and also (later):
  # amavisd restart

With some luck this will reproduce the problem, while showing
a failure reason on the first terminal.
