Hi again, I tried to transfer all my attachments to the filesystem with the script: http://extensions.xwiki.org/xwiki/bin/view/Extension/Filesystem+Attachment+… which IS a core extension (at least developed by the dev team). I'm using jetty, and it fails with this error: /var/cache/jetty/tmp/work/storage/xwiki/XWiki/XWikiSyntax/~this/attachments/img.png/img.png~tmp (Too many open files) I found that jetty had many many open files - it had created and left open the handle on hundreds of files in /var/cache/jetty/data/upload__* Was this tested against a full sized wiki? My wiki isn't very big at all yet, maybe a few dozen pages at the most. Does this happen on a tomcat server? Maybe noone checked it on jetty? Seems like leaving the handle open isn't a scalable solution ... I'm looking at the code for the script, I'd like to fix it somehow... Can someone please give me a tip? cheers Paul
