在某些情况下，它离开 Elasticsearch 而不是 运行 作为服务（几秒钟）。
目前 运行 在 Rackspace 中，我认为可能涉及网络问题（但是，我绑定到特定 IP 地址并使用单播）。
那里有 4 个节点 运行（3 个具有 master=true 和 data=true 以及一个客户端节点）。
谁能告诉我那里到底发生了什么？ Windows 服务器上的版本 1.7.3（客户端节点 1.7.1）。
我怀疑这个问题来自 master left (reason = transport disconnected) 并且它是裂脑，但我该如何解决它？
我找到了问题所在。 Elasticsearch 不容忍 TCP Offloading.
TCP offload engine is a function used in network interface cards (NIC)
to offload processing of the entire TCP/IP stack to the network
controller. By moving some or all of the processing to dedicated
hardware, a TCP offload engine frees the system's main CPU for other
tasks. However, TCP offloading has been known to cause some issues,
and disabling it can help avoid these issues.
禁用 TCP 卸载
- 在Windows服务器中，打开控制面板和select网络
设置 > 更改适配器设置。
- 右键单击每个适配器（private 和 public），select
从网络菜单中配置，然后单击高级选项卡。
列出了 Citrix 适配器的 TCP 卸载设置。
- 禁用以下每个 TCP 卸载选项，然后单击
好的:
- IPv4 校验和卸载
- 大接收卸载
- 大发送卸载
- TCP 校验和卸载
这解决了我的问题。

那是我的 elasticsearch.yml 文件：

在某些情况下，它离开 Elasticsearch 而不是 运行 作为服务（几秒钟）。
目前 运行 在 Rackspace 中，我认为可能涉及网络问题（但是，我绑定到特定 IP 地址并使用单播）。
那里有 4 个节点 运行（3 个具有 master=true 和 data=true 以及一个客户端节点）。
谁能告诉我那里到底发生了什么？ Windows 服务器上的版本 1.7.3（客户端节点 1.7.1）。
我怀疑这个问题来自 master left (reason = transport disconnected) 并且它是裂脑，但我该如何解决它？
我找到了问题所在。 Elasticsearch 不容忍 TCP Offloading.
TCP offload engine is a function used in network interface cards (NIC) to offload processing of the entire TCP/IP stack to the network controller. By moving some or all of the processing to dedicated hardware, a TCP offload engine frees the system's main CPU for other tasks. However, TCP offloading has been known to cause some issues, and disabling it can help avoid these issues.
禁用 TCP 卸载
- 在Windows服务器中，打开控制面板和select网络 设置 > 更改适配器设置。
- 右键单击每个适配器（private 和 public），select 从网络菜单中配置，然后单击高级选项卡。 列出了 Citrix 适配器的 TCP 卸载设置。
- 禁用以下每个 TCP 卸载选项，然后单击
好的:
- IPv4 校验和卸载
- 大接收卸载
- 大发送卸载
- TCP 校验和卸载
这解决了我的问题。
