> Current TcpDiscoverySpi can prolong detection of node failure which has
> several IP addresses. This happens because most of the timeouts like
> failureDetectionTimeout, sockTimeout, ackTimeout work per address. Actual
> failure detection delay is: failureDetectionTimeout*addressesNumber. And the
> node addresses are sorted out consistently. This affection on failure
> detection should be noted in the documentation.
> The suggestion is to represent this behavior in
> https://apacheignite.readme.io/docs/tcpip-discovery. The text might be:
> "_You should assing multiple addresses to a node only if they represent some
> real physical connections which can give more reliability. Providing several
> addresses can 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_. And node addresses are sorted out
> sequentially.
> Example: if you use _failureDetectionTimeout _and have set 3 ip
> addresses for this node, previous node in the ring can take up to
> 'failureDetectionTimeout * 3' to detect failure of current node_."
