No, this is a vanilla 7.0-RELEASE installation with only lpd and ntpd configured. Neither of pf, ipf or ipfw is used. > 2) Have you tried turning off RFC1323 on the RELENG_7 box to see if > the TCP behaviour changes? sysctl net.inet.tcp.rfc1323=0. OK, will do. However, the described problem only happens when the box is resending SYN-ACK after SYN was received and no answer (ACK) was received after the first SYN-ACK. All other connection requests from the same host to the same port (lpd) work without problems. So currently this affects about 0.1 to 0.3 percent of all 3000 - 6000 print requests.
