I don't know if it's anything to do with this, but last time I left it on as an option I got a panic - so it's always off for me now. I use the CPU as timer and I have a dual Xeon box. So I use the SMP but I have phisically 2 CPUs. I don't use HyperThreading. When I ran into this problem the CPU usage was not too high. The load was low and I had 25-50% idle CPU time (top). If I make some load on the macine the ping times grow and none else change. I checked that the ksoftirqd is not eating my CPU. In the next 2-3 weeks I'll try to make a setup with HFSC not HTB maybe it will help (I cant use CBQ on this machine). But there are about 20-25000 tc objects on this machine and it's not a 5 minutes job :-( I haven't any else idea yet :-( Arpad Kunszt ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Are you using a 2.6 series kernel with FC1? IMHO in FC1 the default kernel was 2.4. I think the problem is in the kernel somewhere.

My HTB setup stands about 2500 classes and a total of approx 15000 tc objects. > The script I use now worked for a year without any problems, but since > fedora changed to 2.6 the problems started. Me too. I've think the problem started after I use kernel 2.6.8.1. If I good remember I doesn't have this problem with 2.6.7. The new thing in 2.6.8.1 was the QoS clock source (or similar). I use here CPU cycle counter because I have a fast uplink (1 Gbps). I think maybe this can be the source of the problem. Or the HTB has a bug from 2.6.8.1. If anybody has idea please write to here.
