I removed that file.

For something as simple as:
# yum clean all
# yum update (no new updates)

It had a hell of a time downloading the repo database files and
then it went into a spin loop.  Once I removed FM, it went through,
but slower.  With FM, it was much faster but at the expense
of disconnects, or so it seems.

I noticed that when yum disconnects, it smacked my dovecot
imap connections as indicated in my maillog file (I was also
watching messages log file, but nothing noted there), maybe
its a coincidence, but what do I know!

Really odd.

I will forego FM for now.
