unfortunately  -those two are production machines and I'm limited somewhat in 
my testing. However we are planning on "re-playing" same scenario on testing 
boxes.

those are logs from "induced" "wierd state" (i.e. I intentionally set 
secondary machine's firewall up with rules that cause trouble in the first 
run). Message from 10:38 is the one that floods logs. the rest is appearing 
once or twice here and there. While machine is in that state - it doesn't 
respond to *anything* until secondary is "down".
