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.
Thanks,
Felix

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,
We will try that and get back to you.
On another note, we were also having some slowness problems: the object editing screen
takes around 1 and a half minutes to upload on pages where XWiki.Rights or
XWiki.GlobalRights are located. Taking them out fixes the problem. The access rights
editing page is also slower, especially loading the groups, albeit not as slow as object
editing. I suspect that LDAP might have something to do with it, though I am not sure. Our
XWiki has exploded and now hosts a huge group of people (thanks to you :) ) who are all
mapped by LDAP, which may slow the site down if the LDAP authentication mechanism calls
LDAP everytime a page is loaded, or object edited. Am I on the right track here, or is
this problem attributed to something else?
Thanks for your help,
Felix

Probably it's because you have too many users, the rights objects by
default list all users in a drop-down list, which takes some time to
generate and transfer.
You should edit the XWiki.XWikiRights and XWiki.XWikiGlobalRights
classes and unselect the Uses list option for users and groups properties.
Thanks for your help,
Felix
