TIA :) once a TCP connection gets to ESTABLISHED [ASSURED] state--it will not be removed from conntrack until it times out (after 5 days by default (432000 seconds)), or one side sends a FIN-ACK packet requesting that the connection be torn down. it sounds like you're shutting down endpoints after the connections are setup, but before they have a chance to close them. -j -- "Ah, beer, my one weakness.
