Data base and PHP

[humoba]

After uptade to Wordpress 4.3 i have many problems with the database (MariaDB) and with PHP.

With MariaDB aks me for more resources:

In PHP the memory isn't sufficient, ask me for more memory too

[:error] [pid 32523] [client 189.201.176.57:62738] PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 6387425 bytes) in /home/www/vhosts/site.com/httpdocs/wp-includes/wp-db.php on line 1094, referer: https://site.com

After update, everything it was good.

Thanks for contacting us, @humoba!

The MariaDB log indicates that it crashed at some point, but it recovered immediately.

As for the PHP memory error, it occurred in a call to WPDB, but it could've come from anywhere - somewhere else in WordPress, or from a plugin or theme.

If you run into any other problems, I recommend posting on the ​Support Forums - they'll be able to help distill the problem down to find out if it's a WordPress bug or not.
