Hi,
Did anything come of this? I'm seeing the same thing: 2 x error boxes following a delay until next login software distribution.
The only odd thing I can see in the logs (sdclient.log) is:
Wed, 29 Jan 2014 01:55:43 FlushClientTaskQueue: successfully done
Wed, 29 Jan 2014 22:26:46 Cannot start sdclient for task -1, the task 638 is being processed on the client
Wed, 29 Jan 2014 22:26:46 bind or column index out of range
