CPU usage went to 100%
-
Have a dedicated server with Rackspace – 24 core 48 gb memory. Website is [redacted]
Got a call that our site was super slow and went in and see that server was spiking to 300% load average. We were confirmed that Clouflare was caching most of the site and the majority of requests we are seeing on the server were POST requests going to admin-ajax.php.
We use the Newspaper theme
Started disabling plugins to see if anything changed and when we got to Wordfence, disableing it dropped the load down from 300% down to 12%. The amount of apache processes decreased from over 900 to 544.
We have been using Wordfence for years, but starting with you major version changes with I think it was 7.0. I have also seen a number of other people that have has similar issues.
We deactivated every plugin and the only one screwiing things up was wordfence. We just updated to 7.05 . Whatever you guys have done in the last several updates have made your plugin useless to us.
Spent 4 hours debuging and working with Rackspace and we are 100% sure it is a conflict in Wordfence that is the problem
