If it's running 39 wrappers, it's going to be running a bazillion pollers.

Reboot the machine and see if it behaves better after that (or kill all *.php and *.py processes, but reboot is easier)

I'm not sure where to see that information. We have configured Observium according to the help for installation in Centos 7

That's not what I asked.

How many of those processes are running on the system when it is complaining about connections?

observium had 45 processes configured and was running fine. Previously we had mysql 5.7

Hi 

We perform an update to our DB to mariadb 10.11, but now it show this message
DB not connected, please check database connection configuration.DB Error 1040: Too many connections.

By defaults, Mariadb support only 100 connections, 

How  much connections we must enabled (recommended)?

pd: we changed to 500 connections but the message shows again
