[Devil-Linux-discuss] ksoftirqd 100%

[Devil-Linux <dev...@js...>]

Hi all, 

We just upgraded to latest software on one
router/VPN/firewall. 

I had to change to ipsec-tools instead of *swan, but
else all seemed fine from the 1.2.13 we had before. 

Anyways, as soon as
we put trafik through (VPN) it it become totaly unresponcive, and top
always hangs having either close to 100%si or close to 100% on ksoftirqd.


The system is stale for a minute or so and then clears upp again,
probably because the services runing trafic through it timeout. 

From
watching /proc/interrupts it seem to be the network cards generating alot
of interupts. 

We have tried changing networkcards from 3com to intel. We
even bought a new machine, to change everything but still get the same
problem. 

The new machine works better though as the IRQ only hog one
CPU/core att a time so the system still answers. 

My next step is to try
and recompile Devil-Linux with noapic and try that, but before I go ahead I
thought I might ask here and see if you guys know anything else I could
try. It might be just some silly mistake. 

Kind Regards
