IOS upgrade via TFTP

I am upgrading my corporate PIX 515 to 7.2(4)9 to address some vulnerabilities. I have the new image downloaded into my root directory of the TFTP server on my laptop. Once I try to copy the image over to the PIX I get the following error:

WARNING: TFTP download incomplete
Error reading tftp://10.0.0.250/pix724-9.bin (unspecified error)

I am using the "copy tftp flash" command for my upgrade

Yes, the problem is more than likely that your flash is too small.
Cheers!

What tftp server are you using? I had this issue before using TFTPD and this happend quite frequently. Switch to Solarwinds TFTP (Free) and see what happens.
