Have you deleted history file (logdir/pgpool_status)?
It remembers previous failed status. If you believe your PostgreSQL
and settings healthy, you can delete and try to restart pgpool.

If you still have problem, you definitely have problems anywhere. Look
into pgpool-II/PostgreSQL log for more info.
