I am having repeated FTP failures while transferring a 4G file across a LAN. Swapped out the switch, cables, and NIC's so don't believe hardware is involved. Have tried the default FTP server as well as vsftp and pure-ftp with the same results. NICs tested are em, sk, and rl. How to duplicate failure: Take two 6.1 machines with a 100M lan or x-talk cable and try to FTP a DVD image. The transfer fails around 90% of the time with "450 Error during write to data connection" We have a similar problem when using samba. The failure is not as consistent but always occurs under heavy load. Here is the error: [2006/06/04 22:20:02, 0] lib/util_sock.c:write_data(557) write_data: write failure in writing to client 192.168.163.41. Error Host is down It appears, that the network connection on the server is being reset, but why? And where or how do I find more information?
