Question Problem with system suspension

[samuele]

Hi,
my DS216j NAS hasn't been suspended for a few days. I have already read and verified the information in the guide at this link
DiskStation Manager - Knowledge Base | Synology Inc. and it seems that everything is set up correctly.
How can I investigate and find out which service / option prevents the NAS from going into suspension?

I'm a bit surprised that DNS Server and DHCP services aren't in that list of processes that keep the NAS awake. Any package or service that provides on-demand LAN/WLAN services would seem a likely candidate for stopping sleep.

Using Drive 2.0?

Using Drive 2.0?

I don't use it but it is installed.
On the official Synology forum I saw that the problem could be the new version of Drive Server.

Here and here

I tried right now to disable the Drive Service and I am waiting to see if the NAS goes in suspension.

In my case, I confirm that stopping the Drive Server service will cause the suspension function to work again.
