Hello,
with SpamAssassin 3.4.1, we frequently get the following warning:
```
Fri Mar 11 00:05:06 2016 [-8128] warn: error creating a DNS resolver socket:
Only one usage of each socket address (protocol/network address/port) is
normally permitted.
at Mail/SpamAssassin/DnsResolver.pm
line 434, <GEN38> line 843.
Fri Mar 11 00:05:06 2016 [-8128] warn: dns: unable to connect to
[127.0.0.1]:53, failing over to [192.168.123.254]:53
```
This didn't happen with 3.4.0.
Has anyone else seen this issue? Does anybody have an idea what has changed?
An answer on Stack Overflow [^1] suggests that too many sockets are opened in a
short amount of time. But why hasn't this been a problem before?
Regards
Martin Puppe
