Sorry, they are all as per default, commented out in the config.
There are no long running queries, otherwise they wouldn't be vacuumed/analyzed in due time after running first manual analyze, which updates n_live_tup to match reltuples.
My only remaining suggestion is to closely monitor the Postgres log and see if provides a clue.
I'm awfully sorry, I read the autovacuum manual carefully, it isn't n_live_tup, but reltuples that is taken into account during the calculation.
vacuum threshold = vacuum base threshold + vacuum scale factor * number of tuples
where the vacuum base threshold is autovacuum_vacuum_threshold, the vacuum scale factor is autovacuum_vacuum_scale_factor, and the number of tuples is pg_class.reltuples.
Your first suggestion was to RTFM.
