Thank you Justin!

but... in this case... what is local-worker.bro for?. I understood that 
local-worker is what you are running in the workers... Actually the 
linux process still uses local-worker.bro (which is empty...):

  /usr/local/bro/bin/bro -i eth0 -U .status -p broctl -p broctl-live -p 
local -p worker-1 local.bro broctl base/frameworks/cluster 
*local-worker.bro* broctl/auto

Thank you Justin, I would never have figured out this was the problem...

> Ah!  the files you are putting things in is your problem. Take everything you put in local-worker.bro and local-manager.bro and put it into a script and load that script from local.bro
