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.

> =============
> 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

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.
