Scott--

what Jehiah was telling you is that the output you pasted in shows
that some client (appears to be a Safari browser) is making an http
request to your memcached server.

 All those lines that have the < in front, starting with the GET line
down to X-Forwarded-Server line, are lines coming "in" to memcached.
Memcached is expecting to get memcache commands or queries, but
instead it's getting a request from an http client, which thinks it is
talking to a web server.  When memcached sees each line, it checks to
see if it's a memcached command, and it isn't.  It responds with
ERROR.  That's what the lines marked with > show.

Essentially, the browser is looking for groceries, but it's going to
the post office for them.  The post office is telling you "ERROR: I
don't have any lettuce.  I don't know what you are talking about".

You need to figure out why the memcached on your FC5 box is getting
HTTP requests.  (I'm guessing you can get this behavior by starting up
memcached listening on the port that the web traffic is supposed to be
coming in, but I've never tried that, for what would hopefully be
obvious reasons.)

Perhaps you can look at the one you say you have working on FC5 and
check for differences in your configuration
