CRON jobs keep deleting?

[davidwford]

I noticed the other day that the LED scheduler on my router stopped working. I found this was due to all CRON jobs being deleted apart from 5 Diversion related ones. I did a forced update to all my addons (scMerlin, ntpMerlin, conmon, Diversion, etc.) and they all seemed to be restored. I’ve just checked scMerlin again and they have all been deleted apart from 5 Diversion related jobs. Any idea whats going on or how to fix it?

I'm pretty sure this problem has been discussed before. Use The Better Search function to try and find those posts.

I’ve searched through previous posts, but not sure if anything fits the bill exactly, might just be my lack of knowledge.

Still having the problem, but found out that if i reboot the router, then all the cron jobs are listed. When it goes wrong, just the 5 Diversion jobs are listed. Had the issue again today at the same time as lost all wifi connection to router for a couple of mins, not sure if related or not.

System log from around the time is below, not sure what it means though…

Your log file looks odd. The May 5 entries suggest that the router as rebooted, but it's missing all the other usual boot-up messages. At 13:47 there appear to be 3 copies wsdd2 being shut down which doesn't seem normal.

But probably the main issue is at the being where the router's connection to modem is lost. You've probably go some custom scripts that can't handle that situation. I'd investigate the modem logs first to see if there's a problem there.

I have found that the cron jobs can be lost depending on what event triggers a restart of certain systems.

In this case, open the various event scripts in jffs, find the one that only has the diversion items, and either add the other cron entries to that script or call another script that contains them. Having the same cron entries in different scripts won't hurt, because it'll just overwrite the existing cron job (well, you need to remember to update and keep them all harmonized or you could end up with dupes, I suppose).

When trying to track down what erased my cron jobs a year or so ago, I added a line to the start of each script logger -s -p user.info NOTE WAN-EVENT (change the name of the event to whatever the script is, obvs) to log the event so I would know when a particular event got triggered, so I could add or call the missing cron jobs.

I’ve disabled Diversion via the GUI, and no issues what so ever for a week now. I’ll try re-enabling Diversion and see what happens…
