First, thank you for your reply. This is my dev site and it is on a small
memory VPS, ill get more RAM and see if this fix the problem.
For the info, the file is only 25M, it should not take so much heap space.
I'm suspecting this could be a bug.
The file is correctly imported if i use the web tool. I can upload much
larger files with the web tool without problem. It's only the DAV which
seems bound to memory.
