Here’s an issue we’ve run across a time or two here in support so I thought it would be worth documenting just in case you happen to see it. What happens is that the System Center 2012 Operations Manager Config Service DeltaSynchronization process fails and you see an Event ID 29181 that mentions a timeout exception in the Operations Manager event log on one of the management servers. Here’s an example:
Log Name: Operations Manager Source: OpsMgr Management Configuration Event ID: 29181 Level: Error User: N/A Computer: server.domain.com Description: OpsMgr Management Configuration Service failed to execute 'DeltaSynchronization' engine work item due to the following exception Microsoft.EnterpriseManagement.ManagementConfiguration.DataAccessLayer.DataAccessOperationTimeoutException: Exception of type 'Microsoft.EnterpriseManagement.ManagementConfiguration.DataAccessLayer.DataAccessOperationTimeoutException' was thrown. at Microsoft.EnterpriseManagement.ManagementConfiguration.DataAccessLayer.DataAccessOperation.ExecuteSynchronously(Int32 timeoutSeconds, WaitHandle stopWaitHandle) at Microsoft.EnterpriseManagement.ManagementConfiguration.SqlConfigurationStore.ConfigurationStore.ExecuteOperationSynchronously(IDataAccessConnectedOperation operation, String operationName) at Microsoft.EnterpriseManagement.ManagementConfiguration.SqlConfigurationStore.ConfigurationStore.WriteConfigurationDelta(IConfigurationDeltaDataSet dataSet) at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.DeltaSynchronizationWorkItem.TransferData(String watermark) at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.DeltaSynchronizationWorkItem.ExecuteSharedWorkItem() at Microsoft.EnterpriseManagement.ManagementConfiguration.Interop.SharedWorkItem.ExecuteWorkItem() at Microsoft.EnterpriseManagement.ManagementConfiguration.Interop.ConfigServiceEngineWorkItem.Execute()
This error can occur when the Delta Synchronization process is not able to build configuration within its configured timeout of 30 seconds which could be due to a large instance space.
If this is the case, we can increase the timeout using the following method on all management servers:
In most cases this should allow enough time for the synchronization process to complete.

If delta sync then completes successfully, you should see the 29180 success event
