It could be happending because you are getting traffic to or from TCP
port 1812 that's not Diameter protocol traffic; Ethereal's Diameter
dissector registers for TCP port 1812, so TCP traffic to port 1812 is
dissected by that dissector.  That dissector reports some errors in the
packets to the console window; if the traffic isn't Diameter traffic at
all, then the dissector will find lots of stuff it considers to be
errors.
