21:30 - Fingers crossed for not freezing

Leebut · 24 March 2021 14:13

Hello forum,
Occasionally at around 21:30, my system completely freezes and REISUB, while activated, does not work.
I have the journalctl for the last seconds before 21:30. There is an error (first three lines), but I’m unsure what it means.

Thank you.

Are you running any automated tasks such as cron jobs, or time shift backups?
A regular recurring thing feels like something scheduled interferes.

Hello @Alchemix, thanks for your reply. As far as I can see, there are no cron jobs running at that time.

I do use Timeshift, but yesterday’s daily backup ran at 12:00. Borg runs at 21:00, but the external disk wasn’t mounted yesterday, so it didn’t run the backup task. BackInTime is just too slow, so I always prevent that running when it asks for my password.
