Hi guys, I was wondering if anyone here has had anything similar with ipfw and qmail-smtpd. I have a FreeBSD 5.3 and 5.4 box running qmail and often I can see many connections with FIN_WAIT_1, FIN_WAIT_2, LAST_ACK, CLOSING. On this box I have some ipfw limit rules to allow incoming connections and normal keep-state rules to allow outgoing connections. In the beginning I thought it was being caused by the sysctl net.inet.ip.fw.dyn_keepalive. I then disabled the keep-alive, it seems to have helped but still there are many connections stuck at the FIN stage. Does anybody have any tips on this? Thanks a lot Vini
