These two are just warnings, saying that you have ignore_any_rules turned on in stream5, but you have UDP rules with 
"flow" tracking on.  Not a big deal, Snort resolves that by itself.  

The second being that you don't have ICMP tracking turned on in stream5.  Check out the README.stream5 for more 
information.  The Readme can be found in the /doc directory of the Snort tarball.

This means that there are two (or more (in this case there are 10 rules that deal with http.pub)) rules that track the 
http.pub flowbit.  It looks like you have rules on that check to see if the flowbit is on, but you don't have the rule 
that sets the http.pub flowbit on.

(sid:13473 btw in the web-misc.rules file)

for further information on flowbits, check out the README.flowbits in the above referenced directory.
