SYMPTOMS

When you use the Single Instance Storage (SIS) file system filter in Microsoft Windows Storage Server 2003 R2, you may experience the following problems:
  • On a computer that is under a heavy load, the SIS Groveler service processes file updates very slowly. This may cause the Groveler service to never catch up if the system continues to work under a heavy load over a long period.
  • On a memory-constrained computer that is under a heavy load, the SIS file system filter may cause the computer to stop responding.
  • On a computer that has other file system filters installed together with the SIS file system filter, you may notice that the computer stops responding after you start the computer.

CAUSE

These problems occur when the following conditions are true:
  • By default, the Groveler service works in background mode with low priority. In this mode, the Groveler service can process only a certain number of NTFS file system changes before it backs off. If the incoming rate of changes to the file system exceeds the number of changes that the Groveler service can process, and if this rate occurs over an extended time, the Groveler service may not catch up. At some point, an NTFS file system journal wrap will occur. This journal wrap will cause the Groveler service to miss one or more NTFS file system changes. Missing these changes will cause the Groveler service to rescan the volume. Rescanning the volume will put even more load on the computer. The Groveler service also has a foreground mode. This foreground mode will process NTFS file system changes until it has completed them all. However, the Groveler service cannot currently put itself in foreground mode.
  • The SIS file system filter may cause the computer to stop responding if a work item is paged to the hard disk on a computer that is under a heavy load.
  • Interoperability issues between the SIS file system filter and other file system filters that are used on the computer may cause the computer to stop responding.

WORKAROUND

To work around these problems in Microsoft Windows Storage Server 2003 R2, you can use the Sisadmin.exe tool to put the Groveler service into foreground mode. However, the Groveler service runs in foreground mode only until it processes all changes. After the Groveler service processes all changes, it puts itself back in background mode. Therefore, you must periodically put the Groveler service in foreground mode.

Note The Sisadmin.exe tool is unavailable in other versions of Windows.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
