Samba short read error on "get" binary file

[fdf]

We are running Samba Version 2.2.5 on SCO Open Server V with 17 client PC's doing file transfers (put and get) back and forth. We are baffled with the following samba problem:

1. Error only occurs on 1 of 17 client machines
2. Error only occurs on "get" command; "put" and "dir"
commands work fine on that machine
3. Error only occurs for binary files; text files with
identical names and sizes work fine
4. smbclient "get" command for a binary file fails with:
Short read when getting file \\abs\absrel\xxx.
Only got 0 bytes

The "get" command:

smbclient //POS111/POS111 -UPOS111/POS111% -c "get \xxx xxx"

The result:

added interface ip=192.168.141.1 bcast=192.168.141.255 nmask=255.255.255.0
added interface ip=192.168.141.2 bcast=192.168.141.255 nmask=255.255.255.0
added interface ip=127.0.0.1 bcast=127.0.0.255 nmask=255.255.255.0
getting file xxx of size 512 as xxx
Short read when getting file \\abs\absrel\xxx.
Only got 0 bytes.
Error SUCCESS - 0 closing remote file

Ideas?
