Need system to run 24/7

[Robert McBroom]

This thread has been on before but I lost it. I need my system to run 
long simulations without my intervention. It keeps going to a reboot 
intermittently.  The program has recovery that all is not lost with a 
shutdown but the time getting back to check on the system.  Don't 
remember the setting to tell fedora what to do for always on systems.

[Roger Heflin]

You do not need to tell it anything.    All of my systems run until I
reboot them or the power goes off.

Do you mean keeps going to a "crash", ie not something issuing a
controlled reboot?  If so then you likely have a hardware issue.

Note when I ran large supercomputers with long running jobs any nodes
with weak hardware would regularly crash and have to be repaired or
simply thrown out.

It should never reboot on its own.  But if you don't login, then the 
default behaviour is for the computer to go to sleep after 15 minutes. 
If suspend isn't working, then that could be a problem.  If you aren't 
going to login, then you need to disable the automatic sleep.

Thanks Michael, those changes to sleep.conf seem to have done the trick

Glad it worked for you also. I run BOINC on my machines, and 
having it go to sleep even when machine is running something 
seemed stupid. Seems it was related to Lenova wanting to get 
some kind of higher power saving rating with Linux?? Don't know 
why they made it the default settings. Took me a while to find it 
some time ago.

Would think would only go into effect if machine isn't running 
something.

I recall the default of suspend after 15 mins is a legal/regulatory driven change.

The owner has to opt into keeping a device on by turning off the power saving defaults.

None of the various desktop powers setting menus that I could find 
showed such an option.

I use KDE, where the various options are under the Power menu in
Settings. I've never had the system power down autonomously.

Finally found the setting for "do nothing"

Then the system went to sleep

Not 100% sure, but think the /etc/systemd/sleep.conf settings are 
for systemd and thus doesn't matter which desktop one uses?
Know that my machines are setup with XFCE and they were going 
to sleep after 15 minutes after upgrading to Fedora 39. Not sure if 
Fedora 38 had different default settings, but 38 to 39 upgrade 
changed how the machine worked. Other items like blanking 
screen stayed the same. When upgraded from 39 to 40 the 
sleep.conf setting remained same so no problem..

Don't know if any XFCE or KDE or Gnome or other sleep settings 
would change the systemd sleep.conf settings.

These are the changes that I made to keep machine from not 
sleeping by the default setting.

Is there a good write-up on this?

I'm thinking about options for user-initiated versus automatic idle
sleeping.  You may want to be able to manually do it, and not allow it
to go to sleep when it thinks it's idle.  Or may want to change the
patience it has so that it'll stay running for hours, but go to sleep
if you accidentally left it running for half a day, or controlled by a
battery charge-state monitor.

Looking into the file you mentioned, it seems only related to what to
do when sleep is initiated, rather than controlling if and when sleep
is initiated.

There's https://discussion.fedoraproject.org/t/gnome-suspends-after-15-minutes-of-us... which I have bookmarked.

Yes, I've seen that.  I've already linked to it in this thread.

I meant that /etc/systemd/sleep.conf file quoted in the message I replied to.

As I said:  Looking into the file you mentioned, it seems only related
to what to do when sleep is initiated, rather than controlling if and
when sleep is initiated.

There's some info about systems suspending after a certain amount of
(perhaps ill-conceived ideas of) idleness:

https://discussion.fedoraproject.org/t/gnome-suspends-after-15-minutes-of-us...

But if it's rebooting rather than simply shutting down, I wonder if 
something is crashing?

Quirk of multi os system. Windows is first in the boot/efi list so a 
restore from sleep starts windows not any of the linux systems

You can change that using efibootmanager.

That only applies to hibernation, not sleep.  Sleep doesn't shut down 
the computer, so it doesn't go through the boot process.
