The Tool

I'm running 4.9.3 and have been noticing these errors once every couple of days.

[09-Jul-2019 01:27:41 America/Chicago] PHP Fatal error:  Allowed memory size of 805306368 bytes exhausted (tried to allocate 20480 bytes) in /home/account/public_html/app/functions/fn.init.php on line 864

Line 864 in fn.init.php shows:
 

    $valid_timezone_identifiers = timezone_identifiers_list();

Anybody have any ideas what is going on? I am assuming it cannot populate the timezone list. I am not sure but I think the errors began after I started using redis for sessions.

I am constantly seeing google trying to access these links directly which generally results in a 404 because the file no longer exists because the cache has been cleared.  Shouldn't these pages have a nofollow and/or noindex appended to the links?

I have no idea if it is hurting SEO but it seems google is trying to access the links just as much as any other.
