Summary

The total number of files in the inbox\auth\ddm.box of on the site server has exceeded the standard operational threshold.

This condition increases unless it is resolved. If the file count keeps going beyond the threshold, discovery data cannot be processed in a timely manner therefore computer or user resources might not be added or updated in timely manner.

Causes

The total number of discovery data records can exceed the threshold because:
