Running Nessus 3.0.0 on Fedora Core 4. It was working fine, but recently started giving false negatives.

Do you know when the change occurred? What if anything changed in the Nessus environment (eg, plugin updates, scan configs)? Have you looked at Nessus' logs and/or KBs for the affected hosts to see if they contain any clues?

report vulnerabilities for 11890 (Messenger Service). Using NessusWX client, which is telling me that it is scanning more than that port on each host.

Have you verified that the remote hosts are still running additional services that Nessus should pick up? Is the scanned running afoul of any sort of IPS? Have you done a packet capture while running a scan to see what traffic is being exchanged?
