Hello to list and Patrick ! scuse me first for my bad english:) I'm using the new IMQ code since 2 days, and it's very efficient! but i've experimented a bad problem, that i doesn't manage to resolve. for example I load these simple rules: tc qdisc add dev imq0 handle 1: root htb default 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 500kbit burst 30k tc qdisc add dev imq0 parent 1:1 handle 21:0 sfq tc filter add dev imq0 protocol ip parent 1: handle 10 fw classid 1:1 iptables -t mangle -A PREROUTING -i ppp0 -j IMQ iptables -t mangle -A PREROUTING -i ppp0 -j MARK --set-mark 10 ip link set imq0 up the result in the syslog is (at the first network activity) "kernel: nf_hook: Verdict = QUEUE." and quickly become: "kernel: last message repeated 6 times" the real problem is that I've experimented a silent Crash this morning but before using IMQ this machine was rock stable (months without crash) the only usable log of it is: Apr 8 10:03:55 way kernel: nf_hook: Verdict = QUEUE. Apr 8 10:04:26 way last message repeated 1533 times Apr 8 10:05:27 way last message repeated 2982 times Apr 8 10:06:28 way last message repeated 2808 times Apr 8 10:07:29 way last message repeated 2837 times Apr 8 10:08:30 way last message repeated 2841 times Apr 8 10:09:31 way last message repeated 3008 times >> crash here, pc completely freezed << Apr 8 10:21:08 way syslogd 1.4.1: restart. Configuration: o kernel 2.4.18 with HTB patch, o netfilter/iptables v1.2.6a from CVS, ppp0 is kernel mode pppoe, o iproute2-ss020116 compiled with HTB patch So, is it a bug, or a misconfiguration ? tanks a lot!:) curio / a QoS addicted french guy :)
