Could not deliver signal HUP to process because its pidfile doesn't exist



  • in my DHCP system log I see this on startup

    Apr 21 14:09:37 dhcplease Sending HUP signal to dns daemon(49953) 
    Apr 21 14:09:37 dhcpleases Sending HUP signal to dns daemon(49953)

    Apr 21 14:09:41 dhcpleases Sending HUP signal to dns daemon(68711) 
    

    1st I suspect thats a type in an error message (unkown) should be unknown
    2nd Where do I start with cleaning this up? isn't a hup signal an interprocess message? so dchpleases is communicating to unbound and failing?

    I didn't notice anything interesting in by DNS Resolver (unbound) log



  • This error goes away when I remove the checkmark from DHCP registration in DNS Resolver.  Comes back when I re-check it.



  • Found a reference that this may just be a cosmetic bug. I will ignore it unless issues come up.

    That's what I thought as well.
