The configuration is already sql_mode = NO_ENGINE_SUBSTITUTION.
I tested it.
If you add STRICT_TRANS_TABLES, the number of hosts is 0
If STRICT_TRANS_TABLES is subtracted, it is set to 1 as in the existing problem, and the information of the host is changed from time to time.
It probably makes sense at this point to submit a ticket so we can take a closer look. Please email [email protected] with a link to this ticket. A fresh profile would also be useful, if it is small enough to email.
