Purpose

Confirms an infinite loop OOM issue caused by the combination of Metatags v1.18+ and Search API when using memcache for caching on the search view.

Related issues

• Out of memory error with metatag_view submodule and Search API view
• Out of memory error when used with views, metatag and memcache modules

Install

Prerequisites

• Git
• Lando

Setup

1. git clone https://github.com/CascadePublicMedia/metatag-3245876.git
2. cd metatag-3245876
3. composer install
4. lando start
5. lando db-import metatag-3245876.sql.gz

Reproduction

1. Navigate to http://metatag-3245876.lndo.site/.
2. Search for a term with results: "dolore" (should work).
3. Run lando drush cr.
4. Search for the same term again: "dolore" (OOM exception).

After following these steps the search term will causes OOM executions until memcache is flushed manually with:

lando drush ev "Drupal::service('memcache.factory')->get('default')->flush();"
