We have a file that we FTP on a monthly basis to our I5. It is a positionally formatted file. In the past, we have had no problem with this, but late last year it stopped working. When we try to FTP the full file it gives us an FTP error of 426. The interesting thing is if I split the file in half and try to ftp one of the halves, it works. But the next time I try to FTP the next half, it fails with the same reason. I then cut that file in half and it works again. This cycle is repeated every time I FTP a file in, the next time I have to do half the size of the last file. I am bewildered to say the least.
