Dear XWiki developers and users,
Some of our users are having trouble uploading flash video files larger than 20MB on pages in the wiki. We've noticed either of two things happening:
1) When clicking the file attachment, it leads to a page that says "template does not exist" Or 2) When clicking the file attachment, you are prompted to download it. However, the download file is 0KB.
These symptoms are only happening for flv files larger than 20MB. For more clarification, here is a timeline of what happens:
· User uploads these files · Big files return “template does not exist” error and most flash video files larger than 20MB gets cut down to 0KB · User re-uploads these files · These files work, are able to be downloaded with all the content, are able to be played by the jw player, and the problem, at least for a while, seems to be fixed · A little while later, these files start to fail, seemingly in the order they were uploaded in (somefiles bigger than 20MB get the error message and some files, when downloaded, have 0KB, even though the attachment display says otherwise)
We checked that the maximum attachment size for us was set to 1GB, so we're not really sure what the problem is. Any insight would be greatly appreciated.
You should try to: - increase the memory available to XWiki (attachments take up LOTS of memory, this is a known problem which will be fixed at some time) - increase the max_allowed_packet setting for mysql (assuming you're using mysql) -- Sergiu Dumitriu http://purl.org/net/sergiu/
