アプリケーション ログに次のエラーが記録される。

WARNING ; MACRO ; MACRO-1001 ; Rendering macro exceeded time limit ; System ;  ; com.atlassian.confluence.plugins.macros.advanced.recentupdate.RecentlyChangedContentMacro ; {...}

この問題の解決方法

There's no action required for this alert. However, this information may be helpful when investigating an outage or issue such as a slow performing page or add-on.

Some things you could try:

• If the macro is configurable, you may be able to change the parameters so that it displays less information. 
• If the macro is provided by a third party add-on (app), you may want to report the performance issue to the app vendor. 

このアラートを無視した場合 

This alert is for information only. There's no direct action required, however if the macro does not load data asynchronously, it may block the whole page from loading, which would significantly impact users.
