I upgraded my site to Expression Engine 2 over the weekend (from 1.6.3). The upgrade went well, but since the upgrade, I’ve suffered near round the clock CPU throttling. I went through the routine steps (database repair and optimize) and it did not help. I checked the slow query log, and the following was present almost every time:
UPDATE `ex_online_users` SET `member_id` = 0, `name` = ‘’, `ip_address` = ‘188.143.232.202’, `date` = 1352910496, `anon` = ‘’, `site_id` = ‘1’ WHERE `site_id` = ‘1’ AND `ip_address` = ‘188.143.232.202’ AND `member_id` = 0
Sometimes taking more than 10 seconds. I actually don’t care about this logging. Can it just be disabled?
Also, the IP address in question is from Russia and would not be my usual traffic. Is there a security measure I should take to block access?
Thank you,
Chris
