Hi

I have a bandwidth manager configured on the following system:

                    RedHat 8.0
                    Kernel  - 2.4.20 (Recompiled and I changed the
SFQ_DEPTH to 512
                                                and the  SFQ_HASH 3072
                                                and the PSCHED_CLOCK_SOURCE
= PSCHED_CPU

                    Patches for the kernel  = ebtables
                    glibc-2.3.2-4.80.6

The  system is build to act as a bridge. Qos happens on the outgoing eth0
device to about
175 differant subnets. I am using HTB and I have the following hierachy


                                                Group1
                                                    |
                -----------------------------------------
                |
|
            SP1                                                        SP2
                |
|
-------------                                              -------------
 |      |     |    |                                               |     |
|     |
cl1 cl2 cl3 cl4                                            cl5 cl6  cl7  cl8


Al of the cl belong to a service provider (sp) where they are on shared
bandwidth
all of them have a CIR of 1 and a Ceil of 384kbps.


The problem that I am experiencing , and it happens often lately is that the
Qos slows down and
it doesn't pass any traffic at all. I have to restart the whole system
before it starts working again.
If I stop the tc on the device it works as well which rules out the
bridging.

What could be wrong and is Linux going to handle more than 800 sites on a
40Mbps connection ?
