Do you have Samba patch SMBLXQ1A installed along with the latest network
transport patch NSTGD60A?

You will have more reliable results with bytestream files.

Double-check that you have the patches I've mentioned.

It could be a bytestream emulator "feature" that affects both Samba and
Apache.  The bytesize of MPE fixed ASCII files reported via the POSIX API used
by Samba and Apache will always be greater than the number of bytes read by the
POSIX API due to the bytestream emulator removing trailing blanks.
