The captures show that after 128B.txt is opened that the client tries
to read 4k from it and gets 128 bytes back. It then closes the file.

After opening 256B.txt, it just does an immediate close on the file
(never actually attempting a read). That may be because the file data
is cached (or the client thinks it is), or some other bug.

strace of apache would be the best thing at this point so we can see
what it might be doing differently than "standard" user access.
