High memory usage on mysql 5.7.18 running on ubuntu server 16.04
Posted by: Peter Bukaowski

Hello

I om observing high memory and swap usage on mysql 5.7.18 on ubuntu server 16.04 (64 bits). The server is not heavy loaded with not many connections. I have 4 databases , one for Drupal and 3 custom ones around 1GB each.
I tried to adjust various of settings to reduce memory usage nothing seems to work.
Any ideas/suggestion what can I tune more to reduce memory usage ?.

/Peter
