Error in scheduled reboot

Installing and Using OpenWrt

Just looking through the logs and noticed a lot of cron errors that I haven’t seen before. This is being logged every minute:

Tue Mar 31 10:21:00 2026 cron.err crond[4670]: line sleep 70 && touch /etc/banner && reboot
Tue Mar 31 10:22:00 2026 cron.err crond[4670]: wakeup dt=60
Tue Mar 31 10:22:00 2026 cron.err crond[4670]: file root:
Tue Mar 31 10:22:00 2026 cron.err crond[4670]: line sleep 70 && touch /etc/banner && reboot
Tue Mar 31 10:23:00 2026 cron.err crond[4670]: wakeup dt=60
Tue Mar 31 10:23:00 2026 cron.err crond[4670]: file root:
Tue Mar 31 10:23:00 2026 cron.err crond[4670]: line sleep 70 && touch /etc/banner && reboot

I put this line in Scheduled Tasks on my Linksys e8450s to reboot them back when we were having the “kiss of death” issues:

40 1 * * 0 sleep 70 && touch /etc/banner && reboot

Each WAP (5 total) was scheduled to reboot after 1:00am

Each WAP on OpenWRT on was scheduled 10 minutes apart so finicky wireless IOT clients could home and re-home as they went through the schedule. I can probably remove this task now but it has seemed to help some funky IOT clients.

What is wrong with the cron entry?

Change your option cronloglevel to ‘7’ instead of ‘5’ in /etc/config/system

... And that advice is also mentioned in the 25.12 release notes.

(And it is about a change in upstream busybox)

OpenWrt 25.12.2 - Service Release
