Re: High memory usage on mysql 5.7.18 running on ubuntu server 16.04

Seems to me if a bug were responsible for this, thousands of installations with much bigger demands would be inoperable. Looks more likely to be due to slow queries running into resource walls. I'd turn on the slow query log to find the slow queries, and optimise them.

What's the result of ...

select
concat(round(sum(table_rows)/1000000,2),'m') rows,
concat(round(sum(data_length)/(1024*1024*1024),2),'g') data,
concat(round(sum(index_length)/(1024*1024*1024),2),'g') idx,
concat(round(sum(data_length+index_length)/(1024*1024*1024),2),'g') total_size,
round(sum(index_length)/sum(data_length),2) idxfrac
from information_schema.tables
where engine = 'innodb';
