Hello. I have Moodle 2.6 with cca 50 courses. Every day at 02:00 Moodle makes automatic backups. Everything is OK, but after cca 20th course Moodle make pause for cca 2 hours and then continues. I check server logs for errors, but there are no signs of any problem. Any idea, why is Moodle taking coffee break?

Hi,
I suppose that if you could log cron execution reports, you would have the answer in it. Automatic backups take a long time, and if your script execution time is not defined so long, your cron hangs.
Then, latest cron executions wait some time (1h30 if i remember well) before starting automated backups again...
You can find information about that in file backup/util/helper/backup_cron_helper.class.php in the get_automated_backup_state function.

Hello Séverin, thank you for reply. By script execution time you mean max_execution_time in php.ini?
In cron's log I see this: "Checking automated backup status...RUNNING. Automated backup are already running. Execution delayed." But in process list I don't see cron. Really strange.

You could disable the Moodle cron job in crontab, stop all the pending cron tasks and try running the CLI version of PHP: http://docs.moodle.org/en/Cron#Working_out_the_Moodle_cron_command.

Running cron.php script from CLI took ~20 minutes and everything was OK. The same script run by cron module ended after 10 minutes and then waited cca 2 hours for continue. Strange.
