WPChina on "High CPU Load After Update to v4.3"

Thank you Otto!! I've been part of the WordPress community for almost 10 years, and this is one of the oddest things I have seen. We had a log file grow to 2GB+ and this type of load on one server:

[root@webserver ~]# uptime
 07:08:21 up 59 min,  1 user,  load average: 199.18, 141.22, 76.20

Now things are back to normal here:

[root@webserver ~]# uptime
 07:19:51 up  1:10,  1 user,  load average: 4.24, 48.87, 71.06

I HIGHLY suggest WordPress issue fixes immediately. We notified law enforcement in the jurisdiction one of our clients because part of our log files involved a DDOS support company getting involved and we followed our security policies. More hosts and companies need to be aware of this, because at first glance, it appears like DDOS on a WordPress site.
