Re: [xmlblaster] Connection transition DEAD -> DEAD

Michele,
  I'm now using the latest from cvs. I managed to reproduce the error 
two times out of 30 or so, and don't know what I did differently to make 
it appear. If it happens again and I can reproduce it I'll be sure to 
send you the complete logs.

Thanks,
Aaron
