[pgpool-general: 1157] Watchdog error - wd_init: delegate_IP already exists

Tue Nov 6 00:00:34 JST 2012

Hello

I have two pgpool servers: will-pgpool1 & will-pgpool2 with watchdog enabled

I can start will-pgpool2 first which takes the virtual IP, and then start
will-pgpool1 and all works fine.

But if I start will-pgpool1 first which takes the virtual IP, and then
start will-pgpool2 the pgpool2 server doesn't start.

Both pgpool.conf files are the same except wd_hostname
and other_pgpool_hostname0

Both instances are started as root with -d -n

Below is the log debug output.

Thanks,

Will
