我已经将WSO2 API管理器（2.0.0）安装为2个实例一体化集群。除了周期性我看到控制台上以下错误所有工作的罚款：控制台上的WSO2 API Manager定期错误

从我的观察，它发生，几乎每7分钟

$ grep 'LogMediator STATUS = Message dispatched' /var/log/wso2am.log 
[2016-10-22 00:42:23,445] INFO - LogMediator STATUS = Message dispatched to the main sequence. Invalid URL., RESOURCE = /appInstallOrRemove

[2016-10-22 01:08:26,239] INFO - LogMediator STATUS = Message dispatched to the main sequence. Invalid URL., RESOURCE = /appInstallOrRemove

欣赏任何建议，因为为什么发生这种情况。

INFO - LogMediator STATUS = Message dispatched to the main sequence. Invalid URL., RESOURCE = /appInstallOrRemove

此错误，当你发送一个请求到https://localhost:8243/appInstallOrRemove发生，但目前还没有部署与上下文appInstallOrRemove的API。

更新：如果你看看repository/logs/http_access_<date>.log文件，你会看到一个这样的条目。

- xx.xxx.x.xx - - [27/Oct/2016:09:24:26 +0530] "GET /appInstallOrRemove HTTP/1.1" - - "-" "curl/7.36.0" 
- xx.xxx.x.xx - [27/Oct/2016:09:24:26 +0530] "- - " 404 - "-" "-"

这里，xx.xxx.x.xx是客户端的IP地址。

谢谢。你是对的，如果我发送一个随机的URL到GW API，我能看到类似的错误。但问题是，我无法识别上下文，也无法识别我的客户。我试图收集tcpdump几天，以确定罪魁祸首。但是，我无法追踪任何此类来电。任何建议？ –
