See below.

We open the existing file E:\4996.rra successfully as the source (asking
for no access rights).

...

We presumably detect that the source and destination files are on
different volumes and fall back to copy & delete rather than Unix
rename:
        if (errno == EXDEV && (flag & MOVEFILE_COPY_ALLOWED))
        {
            NtClose( source_handle );
            RtlFreeAnsiString( &source_unix );
            RtlFreeAnsiString( &dest_unix );
            return (CopyFileW( source, dest, TRUE ) && DeleteFileW(
source ));
        }

Therefore, we have now (presumably) closed the source_handle and so we
shouldn't care about how MoveFile opened the file.

But, we cannot open the file this time.

...

And stuff fails from there.

We are asking for slightly different rights the second time we open the
file. I presume E:\ is your temp directory? I'm guessing that further up
the log it was created or left open without the right permissions.
You will have to show earlier traces in your log to determine the real
cause.
