java - Apache Ignite 节点失败 : Failed to read magic header

Question

部署在两台机器上的 Apache Ignite 服务器自动关闭。日志中没有具体线索。我能够在日志文件中看到以下警告消息:

[00:35:14,047][WARNING][tcp-disco-sock-reader-#86379%null%][TcpDiscoverySpi] 无法读取魔法 header (接收到的字节太少)[rmtAddr=/10.96 .36.48:47830, locAddr=/10.96.36.48:47500]

我该如何调试和解决这个问题？

配置:

检查 10.96.36.48 机器上的哪个进程绑定(bind)到端口 47830。例如，netstat -lnp 将在每个监听端口旁边列出 pid 和进程名称。这将在 Linux 下工作。
