We have a Totara 1.1.6 installation, on Windows IIS server.

The cron is set to run via scheduled task, every 5 minutes.

However, it seems that not all cron tasks are achieved. For instance, competency completions are not calculated. When admin runs cron via web (admin/cron.php) these are calculated correctly.

Cron log files does show as if completion should have run. See below:

Any ideas why this should happen?
