Duplicated Query

Hey guys, I encountered a problem where duplicate queries appear once I start php artisan serve. However, after that initial moment, the duplicate queries disappear.

Duplicated Queries

DatabaseSessionHandler.php#97 blogger 1.78ms select * from sessions where id = 'WKCWlQALgymVxwZ1qdb5lsicY4lC5MIyzZVYpxcH' limit 1
DatabaseSessionHandler.php#97 blogger 590μs select * from sessions where id = 'WKCWlQALgymVxwZ1qdb5lsicY4lC5MIyzZVYpxcH' limit 1

So, What could be causing these duplicate queries ??
