[pgpool-general: 1452] pgPool-II 3.2.3 going in to an unrecoverable state after multiple starting stopping pgpool

[ning chan]

Hi All,
After upgrade to pgPool-II 3.2.3 and I tested my failover/ failback setup,
and start / stop pgpool mutlip times, I see one of the pgpool goes in to an
unrecoverable state.

Mar  1 10:45:25 server1 pgpool[3007]: received smart shutdown request
Mar  1 10:45:25 server1 pgpool[3007]: watchdog_pid: 3010
Mar  1 10:45:31 server1 pgpool[3338]: wd_chk_sticky: ifup[/sbin/ip] doesn't
have sticky bit
Mar  1 10:45:31 server1 pgpool[3339]: bind(:) failed. reason: Success
Mar  1 10:45:31 server1 pgpool[3339]: unlink(/tmp/.s.PGSQL.9898) failed: No
such file or directory


netstat shows the following:
[root at server1 ~]# netstat -na |egrep "9898|9999"

Is this a known issue?

I will have to reboot the server in order to start pgpool back online.

My cluster has two servers (server0 & server1) which each of them are
running pgpool, and postgreSQL with streaming Replication setup.

Thanks~
Ning
