Mysql2::Error: Lost connection to MySQL server during query

[fradeski]

I am currently testing minicron with MySQL (direct connection with a external database)
However I have about 1 query out of 4 that goes into connection error.

Can you verify from another program that the connection between the server minicron is running on and your external MySQL server is stable?

It's a galera gluster used with another program as monitoring, teampass, ...
I tried a galera VIP and direct node connection but the result is the same.
