[pgpool-general: 4443] pgpool watchdog arping WARNING: interface is ignored: Operation not permitted

[Travis Kirstine]

I have pgpool (3.4) running in watchdog and everything seems to be 
working fine, however I'm getting some warnings in my log during the 
escalation from standby to master.  The warning seems to be coming from 
the arping command

Is this the expected behavior?
