You have added detect_anomalous_servers to your HttpInspect portion of
your snort.conf.  You are using network clients that HttpInspect
thinks are web servers, but the ports were not defined by
HttpInspect's profile.

Remove detect_anomalous_servers from your snort.conf or define your
HTTP ports properly for HttpInspect and you won't see those alerts.
