Hello, My machine stopped responding while working on pipes. Here's the info I got. # /var/log/messages Nov 30 21:30:58 devel stunnel[670]: pop3s connected from 80.56.52.238:1859 Nov 30 21:31:23 devel stunnel[670]: Connection closed: 8013 bytes sent to SSL, 126 bytes sent to socket Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 1 Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 3 Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 5 Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 7 Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 9 Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 11 Nov 30 21:35:16 devel kernel: dummynet: ++ ref to pipe 11 from fs 15 Nov 30 21:35:45 devel stunnel[670]: pop3s connected from 80.56.52.238:1892 Nov 30 21:35:52 devel stunnel[670]: Connection closed: 2247 bytes sent to SSL, 62 bytes sent to socket Nov 30 22:17:12 devel syslogd: kernel boot file is /boot/kernel/kernel Nov 30 22:17:12 devel kernel: Copyright (c) 1992-2003 The FreeBSD Project.

All rights reserved. .... Because of I had no direct access to the machine I had to call and ask for rebooting it (As I can see, reset button was used) The error occured when I was flushing pipes. I'm sure that there were 2 rules set, both allowing access. ( I just wanted to make sure, that some traffic is controlled by ipfw). Before, few rules used queues & pipes, but all of them have been deleted successfuly (so I assume that I could safely flush the pipes ?) Maybe ony of you had the same problem or maybe I missed with ipfw configuration? Thanks!
