The problem persists, I compared the LOCALE of two identical servers and collation
database and LOCALE of the database server.
They are all the same. but whoever upgrades from moodle keeps sending random duplicate emails.
This is the LOCALE
LANG=es_CL.UTF-8
LC_CTYPE="es_CL.UTF-8"
LC_NUMERIC="es_CL.UTF-8"
LC_TIME="es_CL.UTF-8"
LC_COLLATE="es_CL.UTF-8"
LC_MONETARY="es_CL.UTF-8"
LC_MESSAGES="es_CL.UTF-8"
LC_PAPER="es_CL.UTF-8"
LC_NAME="es_CL.UTF-8"
LC_ADDRESS="es_CL.UTF-8"
LC_TELEPHONE="es_CL.UTF-8"
LC_MEASUREMENT="es_CL.UTF-8"
LC_IDENTIFICATION="es_CL.UTF-8"
LC_ALL=
I think I have a hypothesis. when the process of sending emails is delayed and it runs simultaneously with the next minute, it makes a new sending.
looking at the back of the 2 cron in both I send the same forums.
