We are using XE 1.5 on Tomcat 5.5 on Windows. Tomcat is running as a service. I have uncommented xwiki.temp.dir in xwiki.cfg I tried several different entries including /tmp/xwiki xwiki.temp.dir=D:\XwikiWorkspace80Port\temp\xwiki xwiki.temp.dir=D:/XwikiWorkspace80Port/temp/xwiki where D:\XwikiWorkspace80Port\temp\xwiki exists and is writable and file uploads > 100k (i.e. not handled in memory) do not succeed and time out on read with the following error in the logs, sorry for the length. com.xpn.xwiki.XWikiException: Error number 11008 in 11: Exception while parsing uploaded file Wrapped Exception: Processing of multipart/form-data request failed.
