2011-11-22 10:06:17,054 ERROR [CTP-jwc #814] [909838433] Minor error occurred during synchronization.
Omni.Scheduling.SchedulePostponeException: The remote server returned an error: (503) Server Unavailable. ---> System.Net.WebException: The remote server returned an error: (503) Server Unavailable.

 

Cause

Oracle CRM On Demand imposes a set of "web services on demand limiters" that can limit
