Are you sure it completed? Since cron sends email when a job completes,
possibly some part of your job is hung. Does a 'psauwwx | grep amanda'
show any amanda processes hanging around? Not likely, but you've
already checked the obvious stuff.
Also, check the cron log (might have to change your syslog.conf to
get it to log) and see if there's a stop time as well as a start, maybe
it's erroring out on something before the job completes.
