[1.] One line summary of the problem: IProute hangs after running traffic shaping scripts
[2.] Full description of the problem/report:
I have a server with 3 links to ISPs and 1 link for internal network.
I shape my clients to certain speeds, depending on the time of the day.
I have HTB shaping on each interface, about 2250 classes and 2250 qdisc on each, so it makes total ~9000 classes (HTB) and ~9000 qdisc (SFQ).
I run shaping scripts 4 times/day.
Sometimes it makes a kernel oops, hangs at some 'tc ...' command (it differs).
Then the shaping works so-so (usually it works, but doesn't fully utilize the bandwidth) and every iproute command hangs.
Killing the hanging processes kills them, but still every iproute command hangs, including ip and tc.
Sometimes the server stops forwarding, but usually it does so few hours after kernel oops.
Reboot always helps.
[3.] Keywords (i.e., modules, networking, kernel): traffic shaping, htb, qdisc, networking, kernel

[6.] A small shell script or example program which triggers the
problem (if possible)
my traffic shaping scripts are rather huge and they don't always cause kernel oops. I tried to run them together (so classes and qdisc on every interface were changed in parallel), but it didn't help.
I can send you them if you wish.

[7.6.] SCSI information (from /proc/scsi/scsi) 2 SATA Samsung drives. Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: SAMSUNG SP0812C Rev: SU10 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: ATA Model: SAMSUNG SP0812C Rev: SU10 Type: Direct-Access ANSI SCSI revision: 05
[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
The system is Fedora Core 2.
The default kernel has serious problems with traffic shaping, that was resolved in 2.6.9 kernel line.
The kernel is vanilla 2.6.9.
After recompiling the kernel I recompiled iproute using vanilla
iproute2-2.6.9-041019.tar.gz
I use PSCHED_CPU.
Without recompiling iproute, it hanged every time two iproute commands were run in parallel.
