[LARTC] Strange log messages with CBQ?

[LARTC] Strange log messages with CBQ?

[Martijn Klingens]

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:

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.

Oops, forgot to mention the machine config.

It's a kernel 2.4.16 box using a stock kernel with only the IMQ patch and the 
mangle5hooks patch, and the Cyclades HDLC driver. The IMQ device itself is 
the aggregate of our three 2Mbit HDLC links (hdlc0-2).

Figure out what the initial message is - this just lists the fact that
messages have been suppressed.

Doh... 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.
