Error in scheduled backup of courses

Hi,

I'm getting an error in scheduled bakcups of courses - one course is not backing up and breaking the cron script.

Error from the Totara error log:

How can I fix this to restore the cron script to run again?

When I try to run the cron script manually through the site, I just get a blank screen.

Hi Ira,

Could you try making a manual backup of that course and see if it works, or if you get any other errors. If it does work could you send me a copy of the zip file?

You could also try temporarily disabling the scheduled backup for that course to get the cron running while we look into it.

Finally, it would be useful to know what role assignments the user with id 10330 has in that course, as that seems to be what is causing the error.

As an admin, visit: [yoursite]/user/view.php?id=10330&course=1 to find out which user it is, then have a look at the role assignments in the course admin > assign roles page.

Hi Simon,

I checked the backups server report and the course that was previusly giving an Error status is now showing OK.

Although the front page/general site backup status is Unfinished...

I had a look at the user with ID 10330, they only have a default learner role in 4 courses and NO system wide role. Surely, this wouldn't cause problems

Hi Ira,

The 'Incorrect string "needed" in $status->info, please fix the code' message is a known (and still unresolved) Moodle issue when running backups with developer debug mode turned on, however the backup should work fine if run with debugging turned off.

You were having a few issues with the cron last week, is it working now or are there still outstanding problems?

Hi Ciaran,

Does that bug apply to any option above "NONE: Do not show any errors or warnings" for the debug messages setting, or only if set to "DEVELOPER: extra Totara debug messages for developers"?

I have the Display debug messages currently set to No.

I have disabled the automated scheduled backups at the moment, so the cron script will run.

When the cron was crashing, the cron.pid file had to be removed from the moodledata folder manually. Although, as there were still errors/bugs affecting the cron, it would crash again the next schedule run (every 5 mins).

Don't have the time to check if cron is crashing every hour.

Also I never received an email when I had the "Notify Admin" setting ticked for the Cron watcher.

Hi Ira,

Debug set to NONE or MINIMAL should get rid of that spurious error message.

See my post on the other thread for why the cron_watcher is not running properly...if you can alter the way it is being called and check the email addr4ess on the admin user then at least we should get some information on what is causing your remaining cron problems.

Hi,

I changed the debug setting to MINIMAL and re activated the scheduled backup - The backup failed for 3 courses and has crashed the cron script again sad

I have attached the server error log

I still haven't managed to get the cron_watcher script call updated in the prod server cronjob, so having to request cron.pid be removed everytime its crashed.
