I have not. Until the other day in this thread, I thought they fixed it 
in the newer target versions. I just noticed this behavior was the 
general error handling behavior for all unknown commands yesterday when 
testing your patch. Trying to write up an analysis about why they should 
return a ILLEGAL REQUEST and not drop the connection for unsupported 
commands.
