Seems like cron is letting me down

[MvW]

Not sure whether this is Asuswrt-Merlin related or whether it should be in the Add-ons subforum. Feel free to move it if I guessed wrong. Earlier today I posted how Diversion hadn't update its blocking files nor sent out it's weekly stats, but I just realised the issue is bigger. All the add-on graphs are empty, it looks like yesterday at 10.14 CEST nearly every task run by cron has come to a halt without any interaction on my behalf or other obvious reason.

Looking at the history of graphs over the past 30 days this happens more often, this appears the fifth time since I'm back on board the Asuswrt-Merlin train. Can anyone please help me troubleshoot this? @Jack Yaz, is there any way you can implement a check whether your scripts are still running (it concerns connmon, ntpmerlin, spdmerlin, but also uiDivStats is affected, so I suspect cron is the underlying culprit. Yet, everything looks normal:

I would like things to keep on running without the need for hourly check to see if cron is still doing it's job. For now the only way I know how to fix this is to reboot the entire system, which isn't desirable for several reasons.

Where do I start to troubleshoot this?

Any help is appreciated.

Best regards,
Marco

Edit: Node and main router are running 386.1_2 without any other issues.

If the cron jobs are listed but not running it might be time for a factory reset

See if cron is running.

ps | grep cron

If it isn't start it.

service start_crond

This setup is only a few weeks old, I just rejoined with 386.1_b5, I believe.

See if cron is running.

ps | grep cron

If it isn't start it.

service start_crond

I rebooted just the router and the node, so everything is running again, but will check whether cron is running the next time things come to a halt.

Thank you both for your quick reply.
