  • 我已经在 issues 里搜索，没有重复的issue。

环境信息

  • arthas-boot.jar 或者 as.sh 的版本： 3.1.0
  • Arthas 版本: 3.1.0
  • 操作系统版本: CentOS Linux release 7.2.1511 (Core)
  • 目标进程的JVM版本: OpenJDK Runtime Environment (build 1.8.0_201-b09)
    OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode)
  • 执行arthas-boot的版本: 3.1.0

重现问题的步骤

  1. 在root用户下执行curl -L https://alibaba.github.io/arthas/install.sh | sh，然后运行 as.sh
  2. 选择目标进程序号，提示Attach success.
    telnet connecting to arthas server... current timestamp is 1555896633
    Trying 127.0.0.1...
    Connected to 127.0.0.1.
    Escape character is '^]'.
  3. 运行dashboard或者其它任何命令，均输出“Timer already cancelled.”

期望的结果

如arthas帮助文档上列出的，目标命令的正常输出。

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。

$ thread

使用的是shell是什么版本的？有可能是shell自动输入了ctrl + c 或者 Q ？ 其它命令有问题不？

shell的版本是，GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)
其它Arthas命令的执行，都有问题。
