Sorry for the delay Jeremy. I ran strace on the lowest pid for smbd (I ran
"pidof smbd" to get pids, and used the lowest one of the 4 or so that came

Command was "strace -f -o strace.log `ls /proc/2019/task/ | xargs -n 1 echo
-n " -p`". I then copied a 1.3GB file from the server to my client to
generate traffic. The resulting file was around 93k lines (15MB). I've
copied the first 2000 lines since it looks like the rest are
repeats/similar: http://pastebin.com/raw/2EJsk0An

I can provide the full file as well if required.
