[Pgpool-general] Connection losts

[Rauan Maemirov]

Hi all. I have a problem with using pgPool. I'm using version 3.4.1 (maybe I
should upgrade to II-beta2?).
I'm connecting from php with PDO over persistent connection.
Sometimes I couldn't connect to pgpool. Looks like it doesn't have free
pools, but there are not so much users(over 10, 20).

pgpool.conf

num_init_children = 48
max_pool = 10
child_life_time = 0
connection_life_time = 0
child_max_connections = 0
...

postgresql.conf (version 8.3.1)

max_connections = 500
shared_buffers = 64MB
temp_buffers = 16MB
work_mem = 2MB
maintenance_work_mem = 16MB
max_fsm_pages = 204800
max_fsm_relations = 100
max_files_per_process = 1000
track_counts = on
autovacuum = on

Other options are by default (commented).

What I'm doing wrong?
