I was able to reproduce the state that cannot connect with the error
in the following conditions with ApacheBench.

  PostgreSQL        pgpool-II
  max_connections < num_init_children * max_pool

These variables should set it as follows.

  PostgreSQL         pgpool-II
  max_connections >= num_init_children * max_pool

Will you confirm the max_connections setting of all backends?
