Does it mean that the "thundering herd" problem in accept() appeared again

FreeBSD 7 TCP syncache fix: request for testers ... I've found one of the causes of the network instability of FreeBSD 7; the tcp syncache fails to retransmit SYN-ACK packets.... If the third part of the 3WHS is lost, the client will believe that the connection is in the ESTABLISHED state, while the server will still have the connection in the syncache.... I'd appreciate testing from anyone who has experienced TCP problems with FreeBSD 7, as well as anyone who is pushing significant traffic through FreeBSD 7. ... (freebsd-current)
