Traffic stopped every hour

good morning
I have a question.
I just migrated the node to a new PC with more capacity. During the new installation add the new capacity. The node started and it is working.
However, it stops every hour of the clock (apparently only the traffic and not the node) and is without traffic for 10-15 min. Once there has been traffic, it stays for 1 hour and stops again.
So all the time.
I can see that only files are deleted from the node during the time it does nothing (10-15min).

Before I did not do this effect and I do not know if it is noramal.

Any customers’ behavior is normal, if your node online, not suspended and not disqualified
