This is running in yosemite (current version with updates) and on a MacPro.
Blows everybody out and the computer must be rebooted.
If I look at the Admin Console, the start stop button is gray (or dimmed) and unavailable.
Happens almost daily (sometimes twice) and the last thing the server log displays is "Backup Completed"
There are only 6 or 7 files on the server with the main file being quite large (if that helps).
Any pointers would be appreciated!
P.S. I might have posted this earlier but I cannot find it in the discussions...
