[pgpool-general: 3722] Re: Questions about watchdog

[Gervais de Montbrun]

Hi Wes,

Something must be awry with your configs. Can you share the watchdog relevant settings of your configs?
Perhaps your heartbeat_destination0 and other_pgpool_hostname0 are not set. Just a hunch. Make sure that the first is the hostname of the server you are running on and the “other” points to the other pgpool server.

Cheers,
Gervais
