Amavis just stops and exits

These two events are unrelated. The "Requesting process rundown
after 20 tasks" is normal and happens when $max_requests tasks has
been processed by a child process - the child process terminates,
but Net::Server running in a parent process immediately creates
a fresh replacement process.

The second event looks loks like a normal restart: the process
17612 is shutting down, while the new 8442 is starting.
Something is sending a restart signal to amavisd, perhaps
some cron job or a log file rotator.
