You've got an intruder. Take the machine off the network. Create a backup
for further analyzation. Don't trust the output of installed binaries
like ps. Examine the installation from within a rescue mode.
Also see what "chkrootkit" and "rkhunter" find.
Reinstall unless you really really *really* think you can repair it.
Btw, what version of Fedora is this? And what kind of service is it?
