> After it two nodes works in next way:
> node 1 - sends Discovery requests every 3 seconds:
> [2013-08-05 21:02:00,585] TRACE [TransferQueueBundler,global,_index-subscriber-node01] org.jgroups.protocols.TCPPING            _index-subscriber-node01: sending discovery request to xxx.xxx.xxx.xxx:34383
> node 2 - [2013-08-05 21:02:03,791] TRACE [OOB-2,global,_index-subscriber-node02] org.jgroups.protocols.TCPPING            _index-subscriber-node02: received GET_MBRS_REQ from _index-subscriber-node01, sending response [PING: type=GET_MBRS_RSP, arg=_index-subscriber-node02, view_id=[_index-subscriber-node03|230], is_server=true, is_coord=false, logical_name=_index-subscriber-node02, physical_addrs=xxx.xxx.xxx.xxx:34383]
> And node 1 - didn't get any response and continue to send discovery request every 3 seconds.
> So it necessary to restart node to restore functionality.
> What is interresting - I see much more simmilar exceptions - and in most cases functionality is restored authomatically. Only few of them break a node.
