Erik-

I'm not exactly sure what you mean by "the multiple-file creation of size 0." Are you talking about seeing size=0 in search results? If so, this is the result of a small change we made in 2.5.x versions where servers will report size 0 when, in fact, the server is no longer serving that file. We actually changed this back for 2.5.5 so that the server will still return the file's original size, even though it's no longer shared. In the long run, we will likely change it to dynamically remove these files from the server's file cache, but this is a more involved change.

Is this what you're referring to (seeing files of size 0 in search results)?

Thanks.
