Error while running Psconfig command

[SPWebTemplateSequence] [ERROR] [11/3/2008 2:45:22 PM]: Template PWS#0: Exception occurred in activating features in site with URL “http://vpc01:1234/sites/sitecollection_45/default.aspx” (SPWeb Id=4f0c3dc9-4ec4-4239-a666-4f27a884013c, SPSite Id=684905e9-af2a-46ae-9497-5409b743a915). Skipping this site for template upgrade. Exception: Microsoft.SharePoint.SPException: There can only be one instance of this list type in a web.

An instance already exists. —> System.Runtime.InteropServices.COMException (0×8102003C): There can only be one instance of this list type in a web.

An instance already exists.

OR

When u try to activate feature in particular sites or site collection getting errors :

There can only be one instance of this list type in a web. An instance already exists.


RESOLUTION:

You have to find the feature that is creating this problem and you have to run the stsadm command

stsadm -o activate feature -name PWS -url  http://vpc01:1234/sites/sitecollection_45 -force

After running stsadm command succesfully. Again run the Psconfig command for upgrade and it will work successfully.
