JMeter：JMeter 远程测试失败，错误为 "Engine is busy, Please try later"

Question

我正在尝试使用 JMeter 执行远程测试，但它失败并显示消息 "Engine is busy, Please try later"。

所有机器上使用的JMeter版本都差不多
我之前可以运行远程测试，但是现在无法实现

日志如下：

如果我遗漏了什么，请帮助我解决。

谢谢！

Answer 1

这可能发生在 jmeter-client 和 jmeter-server 之间的连接问题的情况下。

您应该重新启动所有服务器和客户端并从干净状态尝试。如果问题仍然存在，请检查所有服务器上的 jmeter.log 以查看问题所在。

Answer 2

作为 UBIKs 答案的扩展，这里是我运行执行的命令：

在每个跑步者（奴隶）上执行以下操作：
1. kill -9 `pidof java` 这将终止所有 Java 个进程，因此如果有运行个其他应用程序，请小心。

2.cd 进入 apache-jmeter/bin 目录并输入 ./jmeter-server &

那么你应该能够成功地从 master 重新启动你的测试。
