Given that you've reproduced this using different FTP servers, it seems more likely to be a network issue or some hardware glitch (cables? flaky NIC?) than a software issue. Have you asked your ISP about the issue? Can you reproduce by moving ftp to a different port #? (Perhaps some quality-of-service thingy is providing different bandwidth by port...) Does passive versus active FTP make a difference? Anything interesting in 'netstat -s'? -- -Chuck
