<p>Hi All,</p>
<p><br>
</p>
<p>my unbound v1.6.0-3+deb9u2 servers were hit for short periods of time by traffic that generated a lot of log messages that look like</p>
<p style="margin-bottom: 0in; line-height: 100%"> <font color="#000000"><font face="Liberation Mono, monospace"><font style="font-size: 8pt" size="1">unbound: [879:2] notice: sendmsg failed: Invalid argument</font></font></font></p>
<p style="margin-bottom: 0in; line-height: 100%"><font color="#000000"><font face="Liberation Mono, monospace"><font style="font-size: 8pt" size="1"> unbound: [879:2] notice: remote address is <ip address> port 22653</font></font></font></p>
<p>I can not find any clear documentation on this messages. In fact, the whole mailing list archive only has three emails mentioning this message.</p>
<p>Can someone enlighten me on their meaning and shed some light on a possible cause?</p>
<p>Thanks in advance.</p>
<p>Sincerely,</p>
<p><br>
