> We should emphasize that TcpDiscoverySpi prolongs detection of node failure if several IP addresses are set. Actual failure detection delay is: _failureDetectionTimeout * addressesNumber_. 
> "You should assing multiple addresses to a node only if they represent some real physical connections which can give more reliability. Several addresses prolong failure detection of current node. The timeouts and settings on network operations (_failureDetectionTimeout(), sockTimeout, ackTimeout, maxAckTimeout, reconCnt_) work per connection/address. The exception is _connRecoveryTimeout_.
>      Example: if you have 3 ip addresses configured for a node, Tcp Discovery takes up to '_failureDetectionTimeout * 3 + connRecoveryTimeout' to detect failure of this node_".
