[pgpool-general: 216] Pgpool-II killed java client when master make shutdown

[saurabh gupta]

Hi all,

I am using pgpool-II for my project. Everything is working fine i.e.
automatic failover and online recovery.

I have two servers, one is master and other is standby. I am directly
communicating with pgpool-II which connects with master and standby servers.

Now I am inserting records in database using java on the same port where
pgpool-II is running.

When I killed my master node then my java client also killed before
automatic failover.

Logs at pgpool-II

pgpool.conf:

listen_addresses = '*'
port = 5432
pcp_port = 5433
num_init_children = 32
max_pool = 4
child_life_time = 300
health_check_timeout = 30
health_check_period = 10
health_check_user = 'health'
health_check_password = 'health'

Please tell me am I doing anything wrong?

Thanks,
Saurabh
