SV: [LARTC] 2.4.20 htb3 oops

SV: [LARTC] 2.4.20 htb3 oops

[Göran Runfeldt]

I have arranged a serial console with logging to a terminal client, so next
time it happens I will have the output from the panic. 

For the record: 
One of the machines crashed again this night at 11.30 p.m. (local time). 
I noticed that the MRTG graph looks a bit odd:

The total limit is set to12Mbit, as you probably can see if you check the
ruleset in my first post. Even about 2-4 hours before the crash the graph
shows two network traffic "spikes". The first one tops at about 22Mbps
of outgoing traffic on the interface and the second one tops 28Mbps of
incoming traffic. 
Could this have anything to do with the crash?

Many Thanks,
Göran

Hi G?ran!

Unfortunately that is not going to help much since you can't figure out from
the information below where in the code it crashes. Next time, please copy
the entire kernel panic (including stack trace) and run it through ksymoops
or look up the symbols in vmlinux.

Any solution to the problems describe above? Im currently looking into
building a new kernel 2.4.20 with HTB compiled as module in a
production enviroment (2,5mbits average, 6-10mbits/peak). I wont use
it if its broken though?

Unfortunately we have not yet come to a solution when it comes to our problems.

We have had the machines running for more than five days now, without any 
HTB qdisc/classes loaded. This confirms that this is a problem with HTB. 
I have activated the rules again in hope of getting a useful crash dump.
 
I do not know if anyone else has or will have this problem. All I know is 
that we have the problem over here.
