<p>Hello Laurent,</p>
<p>(you might want to anonymize your msg dumps bit on this public list)<br>
</p>
<p>You probably did already this steps, but nevertheless some debugging ideas:<br>
</p>
<p>- capture a longer network trace and compare the network data of a working against non-working case<br>
</p>
<p>- try to see to find a pattern (e.g. does it happens during a certain time, only to certain users or devices)</p>
<p>- have a look to network interface statistics on server and router/firewall if maybe some corruption is caused from an interface<br>
</p>
<p>- have a look to other network services that are using the same network infrastructure to see if they are also affected</p>
<p>Cheers,</p>
<p>Henning<br>
