Covers four cross-site configuration types (Route, Load Balancer, NodePort, ClusterIP), JGroups RELAY2 and GossipRouter internals, and four common problematic scenarios: non-generational GC (Shenandoah/ZGC) mismatches with Data Grid's bursty memory patterns, network glitches flooding the heap with JGroups messages, CPU throttling from undersized containers, and incorrect route configuration. Solutions include switching to generational GCs (G1), configuring take-offline, balancing CPU requests/limits, and using the correct -route-site URL pattern. Also details tuning knobs for each pod type (operand, gossip router, configListener, operator) and troubleshooting steps using oc adm inspect and JGroups trace logging. ## Full article daily.dev links to this article rather than hosting it.
