Profile manager hangs during device setup

Hi,

I have started to use the profile manager. After adding and enrolling several devices successfully, device enrolling hangs during enrolling a new device.

Enrollment is “In Progress” for more than 1 hour - but there is no progress. From the console log of the iPhone I get the following messages:

These messages repeat for ever.

I have deleted the device and did a server reboot. There after I have tried to reinstall the device - whith the same result.

I do suspect that there might be a problem in the database. Does anyone have an idea how to fix this?
