>
> On communication connection breakage TcpCommunicationSpi may try to 
> reestablish connection and if it's failed try to ping remote node. But if 
> remote node is stopping it refuses incoming ping connections.
> In case of concurrent few node stopping there possible case when nodes ping 
> each other and refuse any incoming pings. This lasts for 
> failureDetectionTimeout or reconenctCount that checks in 
> ServerImpl.pingNode() method.
> pingNode() should check if local node is stopping and interrupt pings.
