Cause
The scheduled maintenance job for the ION_Data database fails due to insufficient space on the drive that the tempdb is on.

Resolution
Free up space on the drive with the tempdb to allow it to grow to the size of the ION_Data database.

Alternatively, move tempdb to a location where there is sufficient space. See FA219030 for instructions on how to do this.
