<p>I am running tinc (1.0.19) on a cluster of around 40 servers
(Xen virtual machines in two geographical locations). Overall it
works very well, however yesterday it crashed on two machines in
odd way. I was still able to ping VPN IPs of other hosts from the
two affected machines but “vpn” interface was not visible when I
run ifconfig. There was also no “tincd” process running (at least
ps aux wasn’t showing it). They logged the following for approx. 20
minutes in the /var/log/syslog:</p>
<pre>
<code>Mar 27 01:52:14 us16 tinc.vpn[9528]: Flushing meta data to <peer_host> (xxx.xxx.xxx.xxx port 655) failed: Connection reset by peer
</code></pre>
<p>and eventually:</p>
<pre>
<code>Mar 27 01:53:03 us16 tinc.vpn[9528]: send_meta() called with NULL pointer!
</code></pre>
