error while loading large file

[ian.trac@…]

Downloader seems to be working fantastically on smaller files (<20mb) but dies on my primary release package (~500mb). Not neccesarily sure it's downloader dependent but ideas on how to get around/improve downloader to be able to handle files of this size would be greatly appreciated.

Server 2k3, XAMP (Apache 2.2) Trac .11dev and here's the output from the log:

Thank you very much for your post! I must admit that I didn't try downloading big files since I changed method of file getting from my own to Trac's. So I'll do some tests and you please first of all check if you have newest version of Downloader (check by SVN repository changes log on the end of wiki page).

Thanks!
