I'm exporting some spaces and have one that comes to just under 8GB as an html zip archive. Both Windows and 7-zip report having problems accessing the file: Windows says it's invalid while 7-zip says many of the files use an invalid compression scheme. Is Confluence (4.3.2) able to export large spaces? I notice the 'zip' binary isn't running so I guess it's using ZipOutputStream or similar from Java. In that case, would Confluence be the limiting factor, or would I need to investigate upgrading the JRE?
You don't supposed to have problems on creating the zip file, unless Confluence shows some errors regarding the creation of the file.
I suggest you to check on your logs if Confluence shows any kind of warning or error that can be causing this.
Also check if the same problem occurs when making the same procedure on a smaller space.
The smaller spaces don't have the same problem. The warnings/errors I see during export are:
"WARN exportResource There is no download resource manager to export the resource"
and a few like:
"ERROR [Long running task: Export Space] [xhtml.view.macro.ViewMacroMarshaller] marshal Exception executing macro: toc, with message: [com.ctc.wstx.exc.WstxLazyException] com.ctc.wstx.exc.WstxParsingException: Undeclared namespace prefix "w""
