dns: bad dns reply: Connection refused
The complete error shown in my syslog is:
Oct 20 11:41:44 localhost spamd[2155]: dns: sendto() to [127.0.0.1]:53
failed: Connection refused, no more alternatives
Oct 20 11:41:44 localhost spamd[2155]: dns: bad dns reply: Connection
refused
Up until this time I saw no issues. Running SA 3.4.0 on Ubuntu 14.04.1
LTS
Anyone have any suggestions?

This seems possibly somehow related to an update to the kernel. This
morning there was an update to kernel 3.13.0-39-generic and right after
the required restart I started seeing:
localhost spamd[2195]: dns: sendto() to [127.0.0.1]:53 failed:
Connection refused, no more alternatives
localhost spamd[2195]: dns: bad dns reply: Connection refused
My /etc/resolvconf shows:
nameserver 127.0.1.1
search PK5001Z
I don't seem to be getting any replies on the Ubuntu list, maybe it's
because it seems related to spamd, I don't know. I do know that scan
times are ridiculous
scantime=201.2
Any more ideas or should I just 'wait and see' if it suddenly corrects
itself as before?

Oddly enough shortly after 6am this morning the issue corrected itself
and all is well now it seems.

This happens when a DNS response comes late and ALARM signal
interrupts its decoding. They call it a 'design feature',
I call it bug:

looks like overload of your local resolver

sorry, no, but what i face repeatly are messages like below
in fact only if the machine has more than 1 dns in resolv.conf
configure it to just use 127.0.0.1 and that won't happen

Is your DNS server running on the localhost?
Is it blocked? Does it have enough threads? Does your resolve.conf
contain ONLY 127.0.0.1 (usually that's fine?)
This implies solely a DNS issue to me.

I forgot to add that running this in a terminal:
chris@localhost:~$ host www.apache.org
www.apache.org has address 192.87.106.229
www.apache.org has address 140.211.11.131
www.apache.org has IPv6 address 2001:610:1:80bc:192:87:106:229
www.apache.org mail is handled by 10 minotaur.apache.org.
seems to show that dns is working or doesn't it?
