SharePoint event log- "The Execute method of job definition Microsoft.Office.RecordsManagement.Preservation.PreservationJobDefinition (ID) threw an exception."

The following error is logged every hour in WFE SharePoint server:

The Execute method of job definition Microsoft.Office.RecordsManagement.Preservation.PreservationJobDefinition (ID -------) threw an exception. More information is included below.  The search request was unable to connect to the Search Service.

I checked the SharePoint logs and this error is preceded by the following:

Exception stack trace:    at Microsoft.Office.Server.Search.Administration.SearchServiceApplicationProxy.GetProxy(SPServiceContext ServiceContext)     at Microsoft.Office.RecordsManagement.Preservation.PreservationTask.Run()     at Microsoft.Office.RecordsManagement.Preservation.PreservationJobDefinition.Execute(Guid targetInstanceId)     at Microsoft.SharePoint.Administration.SPTimerJobInvokeInternal.Invoke(SPJobDefinition jd, Guid targetInstanceId, Boolean isTimerService, Int32& result)

The search service is running on the SharePoint  Application server and is disabled on the WFE. Search is working perfectly for all the SharePoint sites. 

I am trying to get rid of this error in the logs. Is this something that can be ignored?

Thanks.
