Hi Marcel, This is a pretty low-level framing issue that definitely should not be happening. Also, your configuration should be fine. Is there anything unusual about the network over which the inter-router connections are communicating? Are you sending large messages?
It might be difficult, but if you can get a packet capture of an inter-router connection during such a failure, that would be very helpful. It looks like the expected delivery-id was bumped prematurely or delivery 6 arrived twice. It will be easier for us to track this issue if you raise a Jira at https://issues.apache.org for this problem. -Ted On Wed, Apr 11, 2018 at 3:14 PM, Marcel Meulemans <m.meulem...@tkhinnovations.com> wrote: > Hi all, > > I am running a three node fully connected mesh of dispatch routers with > 10000 attached clients and I am seeing some unstable inter-router > connections (I am sending around 1000 message per second through the > network).
