No. It is only killed *after* the connection was lost. Unfortunately it is not always reaped immediately. Zombie processes cannot cause load, because they are dead. They only waste some memory and process slots. > 2. Why these Zombies live on my machine? If you care, you can use 0.6.12 CVS HEAD, which differs basically only by a "reparent to init" call right after our thread startup, as it should have been from the very begining. now, the "zombies" are reaped by init almost immediately after their death.
