I have 1.2.2 Build 794 and everytime I run rcdatasync restart I get this result:

Shutting down the DataSync Connector Manager failed
Shutting down the DataSync Web Admin done
Shutting down the DataSync Engine failed
Shutting down the DataSync Config Engine failed
WARNING: Some datasync service(s) had a problem shutting down. Please see the README for details

If I run it multiple time I get different services fail.
The only way to get functional again is a reboot.
Even after a reboot if I run the command i get the errors.
