Hi Faustin,

Debian 10 server @ Linode:

$ zgrep max_open_files syslog*
syslog:Dec 11 12:36:58 ln0 mysqld[699]: 2020-12-11 12:36:58 0
[Warning] Could not increase number of max_open_files to more than
16384 (request: 32186)
syslog.4.gz:Dec  7 06:27:47 ln0 mysqld[31471]: 2020-12-07  6:27:47 0
[Warning] Could not increase number of max_open_files to more than
16384 (request: 32186)

Same warning but slightly different value (32186)
