Strange messages in the wordpress log

From a time I see messages in the log that I do not know why they are showing:
——————————-
Type: PHP Stack trace
PHP 1. {main}() /var/www/vhosts/sendasoft.com/httpdocs/es/wp-admin/admin-ajax.php:0
PHP 2. require_once() /var/www/vhosts/sendasoft.com/httpdocs/es/wp-admin/admin-ajax.php:22
PHP 3. require_once() /var/www/vhosts/sendasoft.com/httpdocs/es/wp-load.php:37
PHP 4. require_once() /var/www/vhosts/sendasoft.com/httpdocs/es/wp-config.php:93
PHP 5. do_action() /var/www/vhosts/sendasoft.com/httpdocs/es/wp-settings.php:450
——————————-
What are these lines in the wordpress log file?
How can I disconnect that these lines are registered in the log?

Thank you very much for the help.
Greetings.
