[pgpool-general: 4557] PGPool-II-3.5 : failed to create watchdog receive socket

[Christophe Le Roux]

Hello,

I'm trying to setup a pgpool-II-3.5 (HA) configuration with postgresql 9.5 backends.

When i start pgpool, I have the following message :

2016-03-16 10:58:40: pid 34741: FATAL:  failed to create watchdog receive socket
2016-03-16 10:58:40: pid 34741: DETAIL:  bind on "0.0.0.0:cslistener" failed with reason: "Address already in use"

Here is the full debug :
