Automatic reload checks without reason…?

[juan]

I have observed automatic reload checks at high hours of the dawn, is this normal?
…
Nov 22 02:45:00 check_reload_status: check_reload_status is starting
Nov 16 03:10:00 check_reload_status: check_reload_status is starting
Nov 16 02:05:00 check_reload_status: check_reload_status is starting
...

Thanks.
