PROBLEM: IRQ balancing with SMP failed with system load
From: dav
Date: Sat Nov 01 2003 - 17:06:04 EST
hi, i've a trouble with Linux 2.4- kernels on SMP station with XEON processors.
Problem seems to be linked with IRQ generated by network traffic, and occurs
after a variable period (a few days or a few weeks, best now is 21 days with
RedHat(9) kernel.
IRQ are not rightly balanced between each processor on SMP RedHat 9/x86 system,
with too heavy load with high network traffic (and so, a lot of IRQs for NICs).
This occurs with a lot of kernel tested (2.4.20, 2.4.21, 2.4.22, 2.4.22-ac4).
At this time, we are running RedHat kernel :
# cat /proc/version
Linux version 2.4.20-8smp (bhcompile@xxxxxxxxxxxxxxxxxxxxxx) (gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 SMP Thu Mar 13 17:45:54 EST 2003
# w | head -1
22:34:33 up 21 days, 8:04, 3 users, load average: 1.17, 1.02, 0.99

This system is used only to route packets (asymetric routing, inside our network to outside only),
without iptables rules (due to this trouble but we've planned initialy to set netfilter rules).
When system is loaded (by process ksoftirq_CPU0), some datas are lost (monitorring system reports
each 10 minuts CRITICAL alerts => 50% of warning report for packet lost).
report trafic when this issue occurs is like this :

Thanks if anyone know how to fix or solve this issue ;-(
At this time, the only answer we found is to switch gateway with H.A
process, and reboot the box with kernel process "broken" ;-(
