I have a mysql slave on AWS/EC2 that receives peak CPU randomally.
I run show full processlits and I get many (few 100s) of processes like this:
'1141944', 'unauthenticated user', 'connecting host', NULL, 'Connect', NULL, 'login', NULL
What is it ?
Any idea on how I can detect what causes the server to suddnely climb to 200 load average?
