Is anyone aware of an issue with the latest 4.3 WordPress release causing stability issues? Seems there is a cron bug that causes database issues and high site server CPU load.
This is the ticket for the issue: https://core.trac.wordpress.org/ticket/33423
There is a hotfix plugin out from WordPress: https://wordpress.org/plugins/wp33423-hotfix/
I have had no issues, but am wondering if installing the plugin makes sense. When they upgrade to WP 4.3.1, the fix will be included and the plugin will automatically disable itself.
