This post is interesting. It appears that we may be having the exact same
problem. We have had a LOT of problems uploading larger files to a z/OS 1.5
machine. Sometimes, it takes a week of repeated tries to get large datasets
uploaded correctly.

Subject: Re: Problem with FTP transfer to MVS (ZOS 1.5)
Missing blocks in the middle? Have never run into that on z/OS, the FTP
would
always fail if there was a problem, not skip blocks. Does your client not
care if
a block was received on theother end?
Look for a pattern if it is reproducible. Are you using the correct
lrecl/blksize?
Any warnings for truncated records? I've seen that with ASCII if the pc
record
is larger than the lrecl. Same file every time? What strange character
pattern
is in the missing blocks? Can you send it to someone to try and upload to a
supported z/OS release?

We are having a problem transferring data files in binary mode from a

Have you seen this type of problem at your installation? Is there a
workaround or APAR?
With certain large files, the destination file is 15-20% shorter than
the original file. Inspection of the files shows that the beginning
and ending data blocks have correct contents, but there appears to be
blocks missing from the middle of the file. The problem was
intermittent but is now 100% reproducible on certain files. Other
binary data files, both larger and smaller will transfer without
problems.
The source and target machines are both on the same network segment
without any intervening firewalls. We have tried several FTP clients
on the source machines with the same results.
I am aware of IBM problem report #PQ29921 (FTP to MVS Data Loss). The
APAR for that fix reportedly applies only to OS/390 v2.7
What can I look for next?
How large is large?
