Question
MySQL takes up 100% cpu, tried everything I could find via google
MySQL takes 100% cpu and I don’t know how to fix it.
I disabled replication: SHOW SLAVE STATUS shows 0 rows
SHOW FULL PROCESSLIST doesn’t show any queries taking long time.
I also tried to fix leap second, reboot server, nothing helped.
I don’t know how to further diagnose
When I run top command, it shows mysql process taking 355%-400% CPU (I resized to 4 cores droplet)
1010 mysql 20 0 2414596 184832 13632 S 355.6 2.3 33:13.13 mysqld
Any help is much appreciated!

Are you seeing anything in your MySQL logs, or in your server’s error or access logs that is out of the ordinary, or is an error?
I have found Server status page in MySQL workbench which gives great mysql core visualisation. I found that my InnoDB Buffer is full there so I increased it and it helped. Thank you.
I tried to diagnose if someone isn’t trying to connect by enabling warning logs before, but found out it’s not an option.
HI @simPod please, how did you solve the problem ? because I have the same issue
@superbodet as I wrote in my comment above, increasing innodbbuffersize helped. I changed to like 6GB or so
