Since upgradeing to 7.00.04 at the end of March my resource log files are now filling up with the following replicated entry.(about 10 per minute). Has anyone else checked to see if this is happening to you also? 

These are causing my backups to fail due to timing out.

2013-04-01 00:10:47,583 [IIS2101][Thread:9][ERROR] DotNetNuke.Common.Utilities.FileSystemUtils - System.UnauthorizedAccessException: Access to the path 'C:\HostingSpaces\xxwebsitexx\xxwebsitexx.org\wwwroot\Portals\0\Cache\Pages\1108_ACABA51644A302FBB325E30E7931BAF8.data.resources' is denied.

   at System.IO.File.Delete(String path)
   at DotNetNuke.Common.Utilities.FileSystemUtils.DeleteFileWithWait(String filename, Int16 waitInMilliseconds, Int16 maxAttempts)

Any idea on what is causing this and more importantly how can I correct this?

Thanks in advance
