在wso2 API管理器中发布API时间歇性失败

标签: wso2 wso2-am

我们在群集环境中设置了WSO2 API Manager 2.1.0。 API发布间歇性失败。 AWS弹性负载均衡器满足从发布者到网关管理器的API发布请求。在分析发布者的日志文件时,它显示以下错误。

<ng-template [ngIf]="obs | async" let-result>
   {{result}}
</ng-template>

以下在网关管理器中找到的错误消息

我们能够通过分析可能的方案请求挂起来解决此问题。我们正在使用AWS EFS在网关管理器和网关工作程序之间共享突触文件(APIM_HOME /存储库/部署/服务器/突触配置/默认)。发布API时,发布者将调用APIGateway管理服务,其中包括EFS文件创建操作。我们已经使用Burst模式创建了EFS。在突发模式下,使用突发信用来确定吞吐量。由于我们的EFS突发信用减少为零,因此EFS没有足够的吞吐量来执行EFS中的I / O操作。将吞吐量模式更改为已配置模式解决了该问题。
