This is an expected behavior. pgpool does not re-connect recovered
node. If pgpool does this, pgpool will repeat connect/disconnect node
forever if it's connected through a flakey network.

This is not what I'm expecting. Can you double check you can connect
to the DB nodes by:

psql -U postgres -h your_db_host_name -p its_port_number template1:

For example,

psql -U postgres -h im-pp3 -p 4003 template1

Also can you show me the all the log after restarting pgool?
