System freeze at midnight

PUE · 2014-12-25 11:10:09

Hi there,

last night, at exactly midnight the whole system froze up, nothing worked anymore. I had to do a hard reset.
I assume that it is related to systemd and its journal since it usually starts to get active at 12, doing whatever, causing lots of disc activity.
/etc/cron.daily/ is empty, so I don't see what else it could be. Any ideas?

systemd 218-1
No log files, the last entry is from Dec 24 23:31:50, so much for the great new journal.

I've asked https://bugs.archlinux.org/task/43219

What timers do you have enabled? Set them to a different time and run them one at a time.

mod note: not a kernel issue. moved to sys admin.

Karol, it is unclear to me to what timers you refer to.

Post the output of 'systemctl list-timers'.

Ah, I see, this is something like cron built into systemd?
Do we have two different cron thingies on the system in parallel now?

$ systemctl list-timers

I have no cron

$ pacman -Qs cron
$

just systemd. See https://wiki.archlinux.org/index.php/Systemd/Timers

When posting configs, code or command output, please use [ code ] tags https://bbs.archlinux.org/help.php#bbcode

It makes the code more readable and - in case of longer listings - more convenient to scroll through.

I have one installed, even though I think I did this particular installation after the switch to systemd.

$ pacman -Qs cron
local/cronie 1.4.12-1

Do you think it might conflict?
Any idea what the issue might be?

karol · 2015-01-07 09:20:49

What issue? If you don't like the timers starting daily at midnight, change it to e.g. weekly runs. If you're not using a package - remove it.

Just having cronie installed isn't a problem. I have both cronie and incron installed and don't have an issue at midnight. Moreover, I am running cron jobs using cronie. Both root and me have active crontab jobs set up.

But, as karol says, if you are not using it, remove it.
