Please also note, that heartbeat processing is independent for each direction of message flow, ie if one side sends many messages there are no heartbeats needed, while the other side may only send heartbeats since it has no other messages to be sent. E.g. a subscription to market data may show this behaviour: First, some MarketDataRequests are sent and then you only receive MarketDataSnapshotFullRefresh etc.
