When I try to open Global Files in File management Action Window I get a System.NullReferenceException on EPiServer.Web.Hosting.Versioning.VersioningFileSummary..ctor(FileItem file, FileOperations fileOp).
My setup is two servers with EPiServer 5.2.375.133 installed. Both joined to same domain. VPP files are stored on a third server in the same domain. AppDomain user is a domain account with modify permissions on the fileshare. Both servers use the same database. Remote events are configured for cache invalidation.
All worked fine until yesterday. The problem started after I uploaded an image, cropped it and saved it with a new name and then deleted the new cropped file. During the delete operation/request there was some kind of performance related problem within the environment. After the delete operation I always get the exception described above when I try to browse Global Files in File management. The VPP for Global Files is a EPiServer.Web.Hosting.VirtualPathVersioningProvider with default configuration.
The uploaded file and the cropped file still exist on the fileshare. The filename of the files also exists in the tblItems table, but the pkID is not the same as the guid on the fileshare. When viewing the site in viewmode, images from global files can be viewed.
There seams to be one or two files miss referenced in the VPP. Anyone knows how to fix this? And should this ever happen?
