Config reloads every day, every night?

I was just looking at my system log on the TrueNAS Core UI and I noticed that for some reason, my TrueNAS install keeps reloading the configuration, even though I am not giving it any commands and it’s just sitting there ideling.

Feb  3 00:00:00 truenas syslog-ng[1331]: Configuration reload request received, reloading configuration;
Feb  3 00:00:00 truenas syslog-ng[1331]: Configuration reload finished;
Feb  4 00:00:00 truenas syslog-ng[1331]: Configuration reload request received, reloading configuration;
Feb  4 00:00:00 truenas syslog-ng[1331]: Configuration reload finished;
Feb  5 00:00:00 truenas syslog-ng[1331]: Configuration reload request received, reloading configuration;
Feb  5 00:00:00 truenas syslog-ng[1331]: Configuration reload finished;

Also, what does all of this mess mean? Why is it throwing this error?

The nightly configuration reload is absolutely normal.

The ntp-4 message is an informational response as your server time is resynced.

See Persistent warning - wsdd WARNING(pid 1450): no interface given, using all interfaces | TrueNAS Community for information on the wsdd message

Why would it need to reload the configuration every night like that?

as for the ntp error, specifically this line makes it sound like the time pool isn’t usable? Or unreachable?

These are the ntp servers is has, I was testing some months ago to get more accurate ntp servers, but then set them back to default.

As for the interface error, that doesn’t quite bother me, although it does seem a bit odd as I have hard-set the Gateway and IP address of the server on my network instead of letting DHCP do that. It only has 1 NIC and that’s the onboard NIC of the server.

I believe it is related to log rotation.

So the logs just, fill up and then empty again? Is that what you mean?

Log rotation is a FreeBSD function - see 14.5. Configuring System Logging at Chapter 14. Configuration, Services, Logging and Power Management | FreeBSD Documentation Portal
