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 ?

And what shows dmesg? Maybe a spu or memory bottleneck?
