[SOLVED] Random shutdowns preferably at night

Dear all,

I have several arch installs running, in particular one of them being the main server of our house hosting quite a few services such as nextcloud docker, http server, NFS and SMB file servers, Lidarr, Radarr, Sonarr, MySQL DB, vdr etc.

This setup has been installed many years ago and has been migrated from a few hardwares already. A few days back I encountered a spontaneous shutdown at night (3am CET). As I wanted to change the hardware anyway I took the opportunity and migrated the system from the original hardware (ASRock BeeBox N3160 w. 8GB RAM) to a new system (Intel NUC8i3BEH w. 40GB RAM). The remaining hardware was the same, i.e. 2TB internal, 2*2TB USB, two DVB-S USB Receiver. Still, the shutdowns persist.

NEW KERNEL

shutdown system down  5.18.16-arch1-1  Mon Oct 31 18:27 - 18:28  (00:00)

As you can see, I have performed an update before the first reboot at 3:31am Nov 11 occurred (new kernel). From there on I had constant shutdowns every night in between 3 and 6 am with one exception: Nov 15 at 11:15am. It is completely weird. I have disabled all cronjobs - no effect. The logs are not helpful. Excerpts:

The server is in the cellar, no kids could reach them and pressing the power button (their sleeping anyway at that time - at least I hope so).

I am a bit puzzled. Could it be the kernel update? Could it be any of the services or any update thereof? Sometimes there is still an open shell dangling before the shutdown, sometimes nobody is logged in. Hence, it must be a service, I assume.

Maybe someone has an idea how to track down this issue further.

Thanks in advance!

Re: [SOLVED] Random shutdowns preferably at night

What does your /etc/systemd/logind.conf look like?
What if you alter all the default shutdowns (and hibernations) to "ignore" (and restart logind)?
Does it happen if you cut the sytem from the network (pull the ethernet, I assume, plug) "over night"?

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Re: [SOLVED] Random shutdowns preferably at night

Thanks for your answer. I have thought about unplugging the network cable for testing. But I should 'remove' bit by bit and see what happens.

I will try unplugging the network cable tonight. Then I will alter the logind.conf, unless you find something suspicious in the data above.

Good catch. See here: Auto Shutdown verhindern

The values I had in setup.conf were higher than zero. But it is not clear to me why it did not happen before. Nevertheless, I have changed them to zero and will not pull the network cable tonight.

Let's see, I will report. Thank you!

Update:

See here: Stromspareinstellungen

There they say that the vnsi plugin resets the values indicated above at each connection. I use the vnsi plugin to connect our kodi boxes to the server. One of these boxes was running 24/7 and has been replaced by something else during the hardware exchange. The something else is not anymore running 24/7 as ist hosts kodi exlusively only (the box used to have some other services running to balance load of the servers). Hence, since a few days these values have not been resetted at night and vdr should have attempted a shutdown. This also explains the varying shutdown times as they have been adjusted by the time the TV box has been shutdown.

That actually has to be it. We will see.

Re: [SOLVED] Random shutdowns preferably at night

Just to let you know that the server did not shut down anymore. Thanks for your help. Marking this as solved.
