I'd try that first. You could run iptraf or wireshark, but I think
you'll get more understandable results with ntop.

Ntop gathers network stats, then presents them in a web page at port
3000 (i.e., start ntop, then browse to MACHINEADDRESS:3000).  I
suspect you'll spot the culprit after looking at the graphs.

You can install ntop via yum from the Dries repository. If you don't
use Dries yet, just put the following into
/etc/yum.repos.d/dries.repo:

[dries]
name=Extra Fedora rpms dries - $releasever - $basearch
baseurl=http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/linux/$releasever/$basearch/dries/RPMS/
gpgkey=http://ftp.belnet.be/packages/dries.ulyssis.org/RPM-GPG-KEY.dries.txt
enabled=0


Then run "yum --enablerepo=dries -y install ntop".
Then run "ntop", and enter whatever password you desire for ntop admin rights.
Finally, browse to port 3000 on the computer running ntop.
