Marc - I would first check that the system is not at disk space exhaustion
       (or invoking user disk usage limit) as inability to write client logs
can cause this condition.
Look in the server Activity Log for any indications.  Beyond that, I would
examine the area of the partition where the backup log indicates that the
process is stopping, and potentially run a disk check against the area.
