我刚刚让一个 Tomcat 实例停止响应（它在被杀死并重新启动后开始正常工作），并且在日志消息中，它看起来就像在它停止响应之前有人正在向它发送无效请求的垃圾邮件。以下是日志文件的摘录：

日志中有相当多的内容。有没有人见过类似的东西？这是一次恶意攻击，还是 Tomcat 实例只是翻转/发疯了？
更实际的是，我可以做些什么，例如在 a ValveorFilter中，检测此类请求并暂时禁止原始 IP 地址？我假设因为 Tomcat 无法解码乱码参数，所以我不能只寻找无意义的参数名称，如果找到就拒绝请求。
编辑
同样的问题再次发生，这次我捕获了一个线程转储。它很长（实际上太长了，无法完整包含在内）：
