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!

@superbodet as I wrote in my comment above, increasing innodbbuffersize helped. I changed to like 6GB or so
