[pgpool-general: 8196] rejecting connections when num_init_children reached

Hi all,

I'm using pgpool v3.4.3 and have the following setup

num_init_children = 25
max_pool = 4

>From my understanding this would allow for 4 unique db user combinations
each with 25 preforked processes / connections.  I have noticed that when
the num_init_childern process count is reached for one unique combination
(db_a) it will block / slow down connections to db_b which have not reached
that limit.

We are using pgbouncer in front of pgpool which is creating persistent
connections which could be part of the problem.

Could I be right
