Wso2 调用APIM Rest API时出错。（在多用户模式下）

我将WSO2 API Manager 2.1.0与MaribDB一起使用

最近我用APIMRESTAPI做了一些测试，比如创建api、更改生命周期和创建应用程序

我测试的目的是检查APIM在收到多个请求时如何工作。 所以我做了一个场景，10个用户同时调用相同的RestAPI

在考试期间，我遇到了意想不到的错误。但是我不知道是什么导致了这种错误

所以我修改了一些代码（am#api#publisher），使它们能够同步工作。 我得到的结果误差较小，但仍有误差

谁能给我一些建议吗？（请检查错误日志）

---

尽管存在上述错误，但几乎所有请求都以200 OK响应。只有少数API状态没有改变。我甚至发现数据库之间的状态不同。（APIMGT_DB=Published，REG_DB=Created）当我们不设置限制层并尝试发布api时，可能会发生此错误。你的情况也一样吗？@DuW不一样。我添加了这样的节流轮胎。，“tiers”：[“Unlimited”]Thx供您评论。@ironrainbow您是否找到解决方案，我也遇到了类似的问题
