The Interconnect router is used with the Hono IOT control framework. Hono uses Vert.x which uses Proton-J for AMQP operations.
The customer describes the failure scenario like this:
"On some event [Hono] will open a receiver link to a specific anycast address and then it's waiting for a message
- A sender sends a message to this address
- Our application closes the reciever link
- This link creation and message sending can be done up to ~200/s before this crash happens"
The crash results in the following error report
2020-04-24 10:33:07.876362 +0000 ROUTER (info) [C439][L4755282] Link detached: del=1 presett=0 psdrop=0 acc=1 rej=0 rel=0 mod=0 delay1=0 delay10=0
