环境信息
  • arthas-boot.jar 或者 as.sh 的版本： 3.6.9
  • Arthas 版本: 3.6.9
  • 操作系统版本: alpine3.18
  • 目标进程的JVM版本: openjdk 1.8
  • 执行arthas-boot的版本: 3.6.9
重现问题的步骤
  1. 进入目标容器
  2. 执行命令./as.sh --agent-id $HOSTNAME --tunnel-server 'ws://Server IP Address:7777/ws'
期望的结果

正常连接可以远程调试arthas

实际运行的结果

实际运行结果，最好有详细的日志，异常栈。尽量贴文本。
