Hi Anyone noticed that today's current has connections jamming like below: Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 33028 196.7.162.25.22 196.7.147.230.3569 ESTABLISHED Or Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 846 41.204.193.40.783 196.7.147.20.4131 LAST_ACK tcp4 0 2707 41.204.193.40.783 196.7.147.136.3009 LAST_ACK tcp4 0 650 41.204.193.40.783 196.7.147.18.2159 LAST_ACK tcp4 0 587 41.204.193.40.783 196.7.147.20.3710 LAST_ACK tcp4 0 587 41.204.193.40.783 196.7.147.18.2155 LAST_ACK It's odd because with the top one, I can still log out and the shell disappears, except for the sshd process, which if I kill it terminates the connection. In the second case, those LAST_ACK connections have been around for about 2 hours. Heavy (well, not so heavy) traffic seems to trigger this on long standing connections. For instance, 'tail -f /var/log/spamd.log' on a busy spamassassin process will do it. Ian -- Ian Freislich
