java.net.SocketTimeoutException：使用 BinaryTCPClientImpl 类在 Jmeter 的 TCP Sampler 中读取超时

问题描述

我正在通过 TCP 协议使用 Jmeter 测试一台服务器，我正在使用 BinaryTCPClientImpl 类发送十六进制编码的字符串数据。发送单个请求时它工作正常。但是，当我尝试对多个请求运行测试时，只有第一个请求到达服务器，而下一个请求由于连接重置和 ReadException 而丢失。无法理解为什么在第一次请求后连接被关闭/重置。 有人可以帮我吗？

在 TCP 采样器级别，我在配置下面做了：

TCPCLientClass : BinaryTCPClientImpl 主机 IP : 10.0.127.21 端口：40221 超时：连接 - 20000 毫秒/响应 - 6000 毫秒 重用连接：选中 关闭连接：未选中 设置 NoDelays ：未选中 SO_LINGER : 空白 行尾（EOL）字节值：10

添加了选中“忽略状态”的响应断言。

请在下面找到调试日志：
