      Planet 4 Bug Report

      Description of the issue: I've been getting emails once in a while (at 
      least 4 in the last 5 work days) about a Wordpress plugin (WP Redis) 
      causing a fatal error (allowed memory size exhausted). As an example, here 
      is the body of one of these emails:

      > Howdy!

      > Since WordPress 5.2 there is a built-in feature that detects when a 
      > plugin or theme causes a fatal error on your site, and notifies you with 
      > this automated email.

      > In this case, WordPress caught an error with one of your plugins, WP 
      > Redis.

      > First, visit your website (https://www.greenpeace.org/canada/en/) and 
      > check for any visible issues. Next, visit the page where the error was 
      > caught 
      > (https://www.greenpeace.org/canada/en/canada/wp-admin/edit.php?paged=2
      > and check for any visible issues.

      > Please contact your host for assistance with investigating this issue 
      > further.

      > If your site appears broken and you can't access your dashboard normally, 
      > WordPress now has a special "recovery mode". This lets you safely login 
      > to your dashboard and investigate further.


      > To keep your site safe, this link will expire in 1 day. Don't worry about 
      > that, though: a new link will be emailed to you if the error occurs again 
      > after it expires.

      > Error Details
      > =============
      > An error of type E_ERROR was caused in line 1165 of the file 
      > /app/source/public/wp-content/plugins/wp-redis/object-cache.php. Error 
      > message: Allowed memory size of 402653184 bytes exhausted (tried to 
      > allocate 63075553 bytes)

      I think 2 things can happen here. We could increase the memory made 
      available to PHP (though I don't have that kind of access myself). In 
      parallel however, it may also be a good idea for someone to go hunting for 
      memory leaks.
