server restart every 01:00

Recently i found out that my untangle server will suspend for some 30seconds - 1min during 0100 at mid night.
Internet connection will pause for a while, both web filter lite and ad blocker scan counter will reset to zero.

Build 9.2.1-amd64

is that ture? does any other admin experience the same? :worship:


*I apologize if i place this thread (question) in the wrong area.
