Problem with Tar file

Hi All, at present I have in my server installed SuSe 7.0 and I have a Tar file that I need to send to another server by ftp. The file has a size of 2.3GB, and when I try to send, it shows the following error o message: not a plain file (ftp). I have tried to compress the file with a gzip -9 and it shows the following error o messages: Value too large for defined data type. What do you suggest, I should do? Is there a limit on the capacity of files that can be sent as Tar by ftp? Is there a limit on the degree to which such a file can be compressed using gzip? Thanks for your help LJ
