> Currently, we have a lot of components having coordinator election ability. Each of these components is electing the oldest node as coordinator. It leads to overloading the oldest node and may be a cause of delaying of some processes.
> The oldest node can have large inbound/outbound messages queue in large topologies which leads to delaying of processing Exchange Latch Ack messages. We should choose secondary oldest node as coordinator to unload the oldest coordinator. This change will significantly accelerate exchange latch waiting process.
