 Subject:  [lvs-users] Kernel 2.6.35 and 100% S.I. CPU Time

  
Hi,

I have recently upgraded from kernel 2.6.27.45 to 2.6.35.4.

Now, any machine which is a backup (that is, receiving connection
updates from another machine) goes to nearly 100% CPU time in Soft
Interrupt.

Profiling the kernel shows the largest portion of time is spent in nf_iterate.

We are using FWMARK rules to specify traffic for LVS.

Is this problem something people are aware of? Does anyone know of a
fix or workaround?

Thanks,
