The processing of exports from the Forefront Identity Manager Synchronization Service failed to complete in the expected amount of time.  

That amount of time can be configured using the {0} attribute of the resourceManagementService element within the Forefront Identity Management Service application configuration file.  The default duration is {1} seconds.  If the volume of requests is very high, then using that attribute to increase the duration would be advisable.  

However, one should investigate why the exports have not been processed in the default amount of time.   Requests created on behalf of the Forefront Identity Manager Synchronization Service should be investigated to determine whether they are taking an unexpectedly long time to process.
