Try stopping Barnyard2 and run it again. If it still does not create them, you can create them yourself by touch 
/path/to /waldo/barnayrd2.waldo
> Do get repeated:
This because you deleted the the waldo file, Barnyard2 goes through all of the logs attempting to read them. The waldo 
file allows Barnyard2 to keep track of these logs.

This is because you are running the stream5 preprocessor with the default memcap. It is a good practice to change the 
default values; based on your network of course.

Thats ok, probably you won't need to.

Did as suggested:

If its possible, stop Snort and Barnyard2, and then delete the waldo. Barnyard2 will create a new one for you.  Did not 
recreate the waldo
 file.

After this line, do you get any other information in the syslog as new alerts are being written into the unified2 log? 
You can also enable
 local syslog output in Barnyard2, just to be sure that Barnyard2 setup is ok.  Did not do this yet.
