Xenforo tends to do that sometimes but I have never really seen anything that breaks before. So I wouldn’t pay too much attention to it and clear the log.
 
I had something similar when performing XF upgrades.
The error was fatal!
It was to do with a settting that I have fogotten the name of.
But for some reason my host had reduced the number.
When they increased the number
The upgrade worked
'
So always do a manual backup before you upgrade

In the MySQL configuration file, you want to increase the value "max connections”. Talk to your host.

For y sharing hosting, I have a limit of 15 connection.
I can't increase the "max connection" just if I will update. So, for the moment I will remain with my sharing hosting.
