1atftp exhibits the well known "Sorcerer's Apprentice Syndrome"(SAS) problem.
2According to RFC 1350, the fix to SAS is quite simple: further copies of the
3acknowledgment for a particular data block would be ignored.

1Fate #303031: Circumvent TFTP size restrictions in atftpd
2The size of a single image file that can be transferred with TFTP is limited to
32^(2*8) *BLOCKSIZE (as per RFC 1350 there are only two bytes for the block
4counter). This is problematic for one of our customers who needs to transfer
5100+ MB Windows images using a TFTP client (NT bootloader) which has a
6hardwared BLOCKSIZE setting of 1432).
