Network Latency problem 2.4.20 (may be related to cls_u32)

Network Latency problem 2.4.20 (may be related to cls_u32)

Post by Maciej Soltysia » Fri, 18 Apr 2003 14:30:25



Hello,

my 2.4.20 machine's network latency after some random ammount of time
increases and makes the processing of packets very slow.
The only cure for it I have devised is to do a
# /etc/init.d/networking restart

On LAN normally i get pings of 0.1 ms. When the machine is under these
conditions, i get results like: 200, 1000, 350, 1100 ms.

I am not sure but it may be related to the cls_u32 module because
I can not unload it after i remove the qdiscs/filters i set up.
Maybe there is a bug in it, maybe some memory is not free'd or something
related.

Anyway, do you have any advice on how to diagnose my problems?
The machine is not workloaded, localhost connections work ok.

Regards,
Maciej Soltysiak

1. IBM x440 problems on 2.4.20 to 2.4.20-rc1-ac3

Helo,
I'm trying to boot from linux kernel 2.4 tree
i've installed rh 7.1 dist, but system seems only 3 procesors, so i made
2.4.20 kernel with smp without NUMA support and i saw 4 processors. Next
2.4.20 with numa support, and system hangs on mounting root filesystem (no
scsi devices found, ide devices lost interruption, no keyboard found etc
etc)
Next 2.4.21-rc1-ac3 without NUMA, 3-processors available
with NUMA support and summit/exa support and clustered apic support kernel
boots, found scsi devices but hangs on it with lost interruption, also with
ide devices and so on
machine has 4 HT processors and 8GB of RAM
any ideas or help?

i don't wat to use 2.5.x kernel.....

regards

Sobczak Wojciech
