WordPress MySQL Stability

For a few days after moving my blogs to self-hosted WordPress, I was seeing somewhat frequent restarts of the MariaDB container. I didn’t see any real indications as to the cause, just a few sql formatting warnings.

I added swap to the host vm, thinking that it may have been memory pressure causing issues. Since I have done that, the problem seems to have gone away. EasyEngine recommends adding swap and a few other tuning tweaks if this problem recurs.
