Oracle Coherence“无法刷新套接字：...”

Question

我正在运行一致性缓存服务器，它在显示成员集和成员列表信息后抛出以下错误。我不确定发生了什么事。 :( 这是我得到的例外。

Stopping cluster due to unhandled exception:     com.tangosol.net.messaging.ConnectionException: Unable to refresh sockets:    [InboundUnicastUdpSocket{State=STATE_OPEN, address:port=191.193.1.127:8088}, MulticastUdpSocket{State=STATE_OPEN, address:port=196.194.184.13:50110, InterfaceAddress=175.143.1.127, TimeToLive=12}, TcpSocketAccepter{State=STATE_OPEN, ServerSocket=191.193.1.127:8088}]; last failed socket: MulticastUdpSocket{State=STATE_OPEN, address:port=172.194.144.93:50110, InterfaceAddress=191.193.1.127, TimeToLive=12}

可能是什么原因？我有兴趣了解是否有可以调查和解决一致性错误的工具和技术。请分享。

这似乎是您的网络/防火墙设置的问题（请参阅http://download.oracle.com/docs/cd/E15357_01/coh.360/e15723/tune_multigramtest.htm）或使用 JDK 版本（某些在此特定网络使用中表现不佳） - 一项工作正常的是 1.6.0_22)。

至于一般故障排除方面，请参阅：
