Unbound and Suricata both crash during overnight operations

[dlevasseur]

Updated to 22.1.2 last Friday.  Each night since, both Unbound and Suricata have been in a stopped state when I get up in the morning.

Here we see me restarting the Unbound service yesterday afternoon at 4:02pm after coming back from a trip.  Then it needs to start the service again at 4:20am?  And then stops the service at 4:34am?  From 4:34 until when I manually start it again in the morning there's 7 pages of statistics all generated within 2 minutes of that service stop.

For Suricata we see me starting it at 4:02pm yesterday (again, when I got back from a trip), no information until the Rule Reload at 2:37am.  Nothing showing the service stopped for any reason and yet here I am starting the service at 4:23am today.

How can I figure out what is causing these services to stop?
