Arch Linux

I'm not sure if this is a bug or just my fault:

Description:
I have a strange situation with pdnsd. If I restart my system pdnsd starts without error but it doesn't resolves IPs. If I restart it with "systemctl restart pdnsd" everythign works fine. The same effect happens if I suspend my PC and wake it up again. Often I have to restart pdnsd.


Additional info:

* PDNS version: pdnsd - dns proxy daemon, version 1.2.9a-pa

* Config:

# machines on your network to query pdnsd.

}

ip = 192.168.1.1; # Put your ISP's DNS-server address(es) here.
proxy_only=on; # Do not query any name servers beside your ISP's.
# This may be necessary if you are behind some
# kind of firewall and cannot receive replies
# from outside name servers.

# that the global timeout option.

Steps to reproduce:

* Rebooting system --> 99% I have to manually restart pdnsd
* Suspend --> 50% I have to manually restart pdnsd
