Yesterday I started using CBQ in production on our firewall over an IMQ device, but since then I get a lot of messages in my syslog like below: On Wednesday 13 November 2002 09:07, root@ism.nl wrote:> Nov 13 08:01:36 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:12:36 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:18:36 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:19:36 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:20:36 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:25:36 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:30:55 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:39:06 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:41:25 firewall kernel: NET: 1 messages suppressed. > Nov 13 08:44:36 firewall kernel: NET: 1 messages suppressed.Any idea what may cause this? It really seems CBQ is causing this. I am running IMQ for a few days now, but without doing actual shaping, and I the syslog remains calm. But from the moment I added CBQ I get lots of these. Doesn''t look like coincidence to me :) Thanks in advance for any help. -- Martijn _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I should have thought of that myself :-/ Anyway, these messages are *followed* by things like Nov 14 17:02:10 firewall kernel: NET: 1 messages suppressed. Nov 14 17:02:10 firewall kernel: protocol 0008 is buggy, dev hdlc1 Nov 14 17:02:10 firewall kernel: protocol 0008 is buggy, dev hdlc2 But there are no messages (besides rather big iptables logs, but what do you expect on a frontend firewall with a class-C behind it ;-) preceding the ''messages suppressed'' warnings. I have no idea what ''1 messages suppressed'' means, much less where it comes from. All I know is that I get it since we started using CBQ.
