Avoiding a STOP SLAVE Crash with MTR in Percona Server older than 5.7.37-40

I am finalizing my Percona Live talk MySQL and Vitess (and Kubernetes) at HubSpot.  In this talk, I mentioned that I like that Percona is providing better MySQL with Percona Server.  This comes with a little inconvenience though: with improvements, sometimes comes regression.  This post is about such regression and a workaround I implemented some time ago (I should have shared it earlier).  This regression is fixed in Percona Server 5.7.37-40, so this is mostly interesting for historical purposes, or if you are running a Percona Server version older than that.

I just posted an article on the Percona Community Blog.  You can access it following this link:

I do not know if I will stop publishing posts on my personal blog or use both, I will see how things go.  In the rest of this post, I will share why I published there and how things went in the process.
