Solution
========
We can increase the timeout using the following method on all management servers:

Make a backup of "x:\Program Files\System Center 2012\Operations Manager\Server\ConfigService.Config"
Increase the timeout values in ConfigService.config for the following:
<OperationTimeout DefaultTimeoutSeconds="30"> to 300 seconds
<Operation Name="GetEntityChangeDeltaList" TimeoutSeconds="180" /> to 300 seconds.
Restart the configuration service
