"No route to host" - interconnect router

Solution Verified - Updated -

Issue

The AMQ interconnect spans across two clusters (PROD and DMZ) with two interconnect routers in each cluster. The DMZ routers are logging No route to host errors.

However, despite the error message being logged, the messages are still being routed through the routers. We have faced the issue in the past. After stopping all four routers and restarting them after that, the error messages weren't appearing anymore.
