[Pdns-users] PowerDNS core dumps on FreeBSD 10.1 in a Jail when master=yes

[bert hubert]

Hi,

The story here is:
>> Mar 26 13:10:35 Exiting because communicator thread died with STL error: Creating local resolver socket for ::, does your OS miss IPv6?: Bad file descriptor

PowerDNS can’t generate an IPv6 socket. You can probably solve that by setting: query-local-address6=

In the config file. This will disable PowerDNS from attempting to open up an IPv6 socket for notifications.

Can you let us know if that helps?
