+title: "Bound EventBusKafka consumer startup concurrency"
+summary: >
+  Bound runtime Kafka consumer startup concurrency and retry transient consumer start failures so cold
+  runtime boot does not stampede the group coordinator and crash-loop when a single consumer times out.
+  The implementation is carried by omnibase_infra PR #1795 with contract-backed configuration fields on
+  ModelKafkaEventBusConfig and kafka_event_bus_config.yaml; no new environment fallback path is introduced.
