We host our community on a web farm of 3 servers. Our images are on a centralized content server so we've mapped /filestorage to a UNC share. This works fine most of the time, but about once a week our images in blog posts, etc won't show up. When I try to hit a full path URL (that references a file using the cfs-filesystemfile.ashx image handler) I get a 404. However when I try to access the file without the handler by referencing the complete file path - http://mydomain.com/filestorage/CommunityServer.Blogs.Components.WeblogFiles/00/00/00/00/12/... the file returns just fine. We know this is therefore not an issue with the UNC share disconnecting but an issue somehow in the community.
Does anyone have any suggestions as to what might be the issue? Thanks!
