I haven't seen any signs of such problems with 4.10. 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
Have you asked your ISP about the issue?
Can you reproduce by moving ftp to a different port #? (Perhaps some

Does passive versus active FTP make a difference?
Anything interesting in 'netstat -s'?
