I had the chance to see a 'top' running when crashing and the memory (I got plenty =16GB) was only used about 1/4. But the CPUs are used at full capacity ! Do you know if it is SW or HW issue ? It could be a coincidence but my clock is running crazy. I have got some huge offsets recently and I am trying to solve this other issue right now. (AFAIK there is no reason it could be link to the iptables kernel paging request) -- Leo Cavaille -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
