During testing of SharePoint 2013 I experienced the Application Event Log errors below. When the errors occurred I was unable to run a User Profile Synchronisation with Active Directory.
Event ID 6398, category Timer
The Execute method of job definition Microsoft.Office.Server.UserProfiles.UserProfileImportJob (ID 0afab701-a201-4df9-bfc7-590838da8809) threw an exception. More information is included below.
Generic Failure

Event ID 1001, category None
Detection of product ‘{90150000-104C-0000-1000-0000000FF1CE}’, feature ‘PeopleILM’ failed during request for component ‘{1681AE41-ADA8-4B70-BC11-98A5A4EDD046}’
The resolution is to grant read access to the Network Service account to the c:\Program Files\Microsoft Office Servers\15.0 folder

Thanks! 🙂
Thak you!
Worked very good on Sharepoint Server 2010
Is recommended to check that security assignment on 15 folder after each CU/SP install on 2010/2013.

Thanks! It worked.
Although adding NETWORK SERVICE to WSS_WPG group is more effective. Otherwise you will have to grant access again, every CU applied to Sharepoint 2013.
Thanx man! was stuck in the issue since one week.. finally resolved !!
