This message is displayed when an [Index Block](https://www.hannonhill.com/cascadecms/latest/articles/content-authoring/blocks/index-blocks.html) in the system renders a large amount of data and reaches the limit configured in the system Preferences. The size at which the application will stop rendering an Index Block can be configured by doing the following:

1. Navigate to **Administration > Preferences > Content**.
1. Under **Index Blocks**, locate the field **Maximum Rendered Size of an Index Block (MB)**.

> **Note**
>
> We recommend keeping this setting under **15MB** if at all possible. Values larger than this may cause Index Blocks to grow to sizes which can result in performance degradation.
