(OT?) Tweaking MySQL57

[Bill Christensen]

Hey folks,

I recently updated one of my servers to MySQL57.  Most of the sites on 
the server are WordPress - everything is up to date. Most of the time 
it's working fine, but a too large percentage of the time I'm getting 
"Error establishing database connection".  A short time later it'll work 
fine with no changes.  Traffic is not extreme.

So apparently some MySQL setting is not correct.  I tried to find a 
place to adjust memory or thread count etc in my.cnf, but there was 
pretty much nothing in that file.  Perhaps I was looking in the wrong 
place?

Any hints will be greatly appreciated.

Thanks!
