NOTE: This bug report is for Confluence Cloud. Using Confluence Server? See the corresponding bug report.

Summary

A page with the "Content by label" macro, combined with an Excerpt Display of "Rich content", will render itself leading to a stack overflow.

This causes:

high CPU usage with more than 10MB of log every second.
Confluence becomes unresponsive until the overflow finishes.
Going to the page can also return an Error page when the page is displayed.
The page may render with infinite traces of itself.
In Cloud the page will automatically try to refresh every 2 minutes if window is left open and will trigger the problem again.

Environment

Confluence 6.0 or 5.9
Content by Label macro

Steps to Reproduce

Create a new page
Add a "Content by label" macro, configured as:
- Label: "testing"
- Excerpt Display: "rich content"
Save the page
Add a label to the page: "testing"
Refresh the page (May require 2 or 3 refreshes for the label to be updated)

Expected Results

Page renders quickly and no error are shown in the logs.

Actual Results

Log shows many errors:

Notes

Wasn't happening in Confluence v5.7 and v5.8.10 because the macro didn't have the 'Rich Content' excerpt.
This is the Macro setting:

Workaround

User a different 'Excerpt Display' option in the macro.

To open the page directly in edit mode:

get the contentid from the database (Cloud customers please contact Cloud Support)

select *  from content where title like 'Title of the page' and content_status = 'current' and spaceid > 0;

use the 'contentid' as the page id value in: https://<confluence-url>/pages/editpage.action?pageId=
