GOautodial Open Source Omni-channel Contact Center Suite

Hello, I am writing in this forum looking for support, thank you very much in advance.

I have a Go autodial in version 3.3, with 40 agents and some inbound campaigns.
At the beginning of the day everything works correctly, but when time passes, it marks this error
in the agent web interface.

cannot connect to local mysql server through socket

I monitor with a htop, and everything looks stable, but at the moment of failure, you see the mysql that fills the entire processor to 100%.

which may be?

I need to apply this command,
service mysqld restart
