Greetings, I have a friend who is having problems with a service he's running. He gets billions and billions of connections to this service a day. Somewhere between 10^8 and 10^9 connections, he notices that his servers lose the ability to accept new connections. These are TCP connections. This is with FreeBSD 6.1R. My first question is: does anybody know if the fixes to -current/7.0 have fixed this? Is there a fix that can be back ported? He's currently working around the problem by having a number of different machines that reboot in a round robin fashion, but would like a better solution. Warner
