[pgpool-general: 4929] Re: Pgpool and IP bonding

[Muhammad Usama]

Hi

>From the pgpool-II logs you shared apparently the pgpool-II startup failure
is because of watchdog fails to bind to the TCP address(most probably
because of the port number is already in use), but unfortunately because of
a bug the error message of bind failure was not printing the correct reason
for failure. I have committed the fix for the error reporting problem in
master and pgpool-II 3.5 branches.

Can try building from source code and share the logs when the problem
occurs.

Muhammad Usama
