推荐答案

要主动，我假设您正在运行ubuntu.在这种情况下，键入以下内容:

To be proactive, I'll assume you're running ubuntu. In that case, type the following:

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

如果您没有运行ubuntu，我建议您以与运行目标进程相同的用户身份运行jmap

If you're not running ubuntu, I'll recommend that you run jmap as the same user as ran your target process
