[PGPOOL-II] Problemas con manejo de conexiones

Hola a tod(at)s,

Estoy presentando un problema con el manejo de conexiones a nivel de
pgpool, me está arrojando el siguiente error en el log de pgpool.

[[No Connection]] LOG: child exiting, 100 connections reached
[[No Connection]] LOG: child exiting, 100 connections reached
[[No Connection]] LOG: child exiting, 100 connections reached
[[No Connection]] LOG: child exiting, 100 connections reached
[[No Connection]] LOG: child exiting, 100 connections reached

[[No Connection]] LOG: child exiting, 100 connections reached

Adjunto configuración actual de los parámetros correspondientes al manejo
de conexiones.

process_management_mode = dynamic
num_init_children = 900
min_spare_children = 10
max_spare_children = 20
max_pool = 4
#child_life_time = 3min
child_max_connections = 100
connection_life_time = 180
client_idle_limit = 180

En postgres tengo configurado el max_connections = 1000.

Agradecería alguna sugerencia acerca de una mejora en la configuración para
evitar este error de conexiones rechazadas.
Mencionar además, que actualmente no se han superado las 300 conexiones
activas.

Saludos.
