Thanks Brian,
Could well be the problem. I deleted the custom template and rebooted the system and have no problems so far but the 24 hours have not yet passed. Once it doesn't reoccur I will make the custom-template again and see if it works.
Next thing I would like to look at is if it is possible to change the 24 hour scan to just scanning the user directories and maybe the ibays. That shouldn't be too difficult but if someone allready made the syntax work I'd be happy to read about it. Thanks for all the answers.
regards,
Jan
