Event ID 6 — BITS Cleanup Task

  • Article

Applies To: Windows Server 2008

BITS (Background Intelligent Transfer Service) Server limits the number of upload sessions that can exist concurrently for a user. If the number of sessions for a user is more than this limit, Task Scheduler is triggered to perform the BITS Cleanup task. Task Scheduler scans the directory and keeps the first number of sessions it encounters. When the number of encountered sessions equals the configured limit, the rest are deleted. By default, Task Scheduler is set to clean up every 12 hours, an interval that can be configured by the administrator.

Resolve

Check if the sessions directory exists

To resolve this issue, check if the sessions directory exists:

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

  1. Ensure the directory corresponding to the vdir exists:
    • On the BITS Upload page, click the Content View tab at the bottom of the page.
    • Confirm the directory corresponding to vdir exists.
  2. Verify that the job folder with the corresponding GUID name is not in use by any other program.
  3. If the physical directory for the vdir is a remote share, verify that the connect as user name and password are correct.
  4. Run CleanUp task again:
    • Click Default Web sites, click vdir, click the Features tab at the bottom of the IIS Manager screen. Click BITS Uploads.
    • Click Run CleanUp Task.

Verify

 To verify that the task scheduler has cleaned up all the stale data in BITS:

  1. Ensure that bitsmgr.dll is present in %windir%\system32.
  2. Open Task Scheduler. From the Start menu, right-click My Computer, and then click Manage. Click Task Scheduler.
  3. Verify that a task with name starting with BITS_{vdirname} exists.
