[galaxy-user] can't download big files

Hello everyone, We have galaxy-dist-17d57db9a7c0 installed on our Mandriva 2009 64bit. There are 2 big fasta files, file A is 4.4G and file B is 3.3G which I tried to download without success. I've used browser download,including mozilla,IE and Chrome,also from suggestion by Jennifer: linux command: wget and curl -O.None of them work. For file A,the downloaded file size is always 450M(9% of total size),no matter which way ( mentionedabove )I use, For file B,the downloaded file size is 0 byte. Following is the error report by :curl -O curl: (18) transfer closed with 4294967296 bytes remaining to read Any help will be very appreciated. Allan
