>            Reporter: Yakov Zhdanov
>            Assignee: Ilya Kasnacheev
>
> There was a GC pause on client that caused servers to drop client due to 
> inability to establish TCP communication connection. Then it took some time 
> for client to detect that it has been dropped. During that time client many 
> times attempted to connect to server which can be seen in the logs. After 
> client detected its drop and reconnected servers fired node added event and 
> no log flood can be found any more.
> We need to find out why client was reconnecting via communication and did not 
> detect the drop for such a long time.
> I hope this can be reproduced in test:
> * start 2 servers
> * start client
> * suspend all client threads with Thread.suspend() - just filter threads of 
> current JVM by name and suspend ones belonging to the client.
