Thanks to all for the replies.
For Bruce Rosenthal: I cannot strace the ipvs_syncmaster since it is a
kernel thread and strace IMVHO doesn't work.
I'm doing some tests with Debian kernel 2.6.8-2-686-smp and the
daemons starts and CPU load is very low (near 0.0) as it should be.
For Horms: I've tryed also non-SMP kernel 2.6.11 (always debian) and
the result is the same (100% cpu hog). May be I should try to disable
Hyperthreading to be sure that it is not the cause. Are you using a
Debian Kernel 2.6.11 or some other version? (Debian kernels are
slightly different from stock Linus' kernels)
More later.
Regards,
Luca
