svn source check out fail

[lakedai]

when i use command
              svn co svn://svn.alfresco.com/alfresco/HEAD/root
to check out the source code, it always fail after about 600M files had been downloaded.

the error message is something like this:

svn: can't open file “root/projects/web-client/source/web/scripts/ajax/dojo/src/i18n/currency/nls/.svn/tmp/text-base/JPY.js.svn-base”: operation not supported

my environment is ubuntu 8.04.

does anyone knows what's the matter?

… I use the command as follows:

svn co http://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD  (it works for windowsXP with silk-svn and Ubuntu 9.10)

… without the   …/root  at the end.

Good luck,
Ralf
