[Bug 1551351] Re: dhclient does not renew leases

[Stefan Bader]

Looking at the changelog history of bind9, the change to 9.10 looks to
be older (around December last year) but then only a recent upload to
isc-dhcp mentions "Link with the non-export bind9 libraries". Which I
think we can assume is what causes the problem. That went to the archive
around noon on Feb-28th which would match my time-line of noticing it.

Title:
  dhclient does not renew leases

Status in isc-dhcp package in Ubuntu:
  Confirmed
Status in isc-dhcp source package in Xenial:
  Confirmed

Bug description:
  Release: Xenial

  I think this only recently started after some bind9 updates triggered a rebuild. When booting dhclient gets started and acquires an IP address, but it does seem to lock up somewhere as it does not renew the lease.
  In my environment I set the lease time to 5 minutes, so I notice such things rather soon. I looked on the dhcp server side but saw any further dhcp messages come in from the client side.
