[pgpool-general: 3734] watchdog failover fails - not switching delegate IP

[Janusz Borkowski]

Hi!
I use pgpool 3.4.2-1
When the Active host 0 (.189) gets its network disconnected, the Standby host 1 (.188) does not switch the delegate IP. Standby watchdog does not realize that Active is not available:
[root at ib-wawa-188 ~]# pcp_watchdog_info 2 192.168.10.188 9898 admin pgpool 0
192.168.10.189 9999 9000 3

In the Standby logs I see repeating every few seconds indefinitely:

Is it known that watchdog failover does not work when network connection to Active gets down?
