Dead services are not getting removed

[Ben Scott]

While using discovery for my application, it would seem that dead service instances are not getting removed.

I had two of my service running:

$ consul members
host1.example.com 192.168.0.100 alive client 0.3.0 2
host2.example.com 192.168.0.101 alive client 0.3.0 2
# other members ...
$ iex
iex> Discovery.Directory.services
%{"my_app" => #HashSet<[:"[e-mail]",
   :"[e-mail]"]>}

Host1 died and I forced it to leave the cluster with:

$ consul force-leave host1.example.com
$ consul members
host1.example.com 192.168.0.100 left client 0.3.0 2
host2.example.com 192.168.0.101 alive client 0.3.0 2
# other members ...

Unfortunately, at this point Discovery has not realized that the service on host1 is no longer available:

$ iex
iex> Discovery.Directory.services
%{"my_app" => #HashSet<[:"[e-mail]",
   :"[e-mail]"]>}
