Issue with Scheduled tasks

Dear Forum,

After upgrading to 1.8.4 today i got a error after running , archive.php

[2012-09-18 15:57:08] [0d369ea7] SCHEDULED TASKS

To my knowledge i never enabled any scheduled task within Piwik, so it is a bit of a mystery where this comes from. Any ideas anyone?

Regards Mike

Can you please check your server error logs to check what the error is ?

Piwik uses scheduled tasks for a few things: keeping DB clean, sending email reports, etc.
