hmm...  I have restarted the operating system with CentOS's original kernel and
done again my experiments. I found that bug has not occurred again.

I don't know why. Maybe, the traditional libpcap has no provided
enough capability
like PF_RING. Or, perhapse something wrong is indeed in patched kernel or Dell
hardware drivers.

BTW, could you tell me what OS distribution you used in your testing PF_RING,
RedHat AS4 or Others? And what kernel source codes are downloaded, from
vendor's websites or www.kernel.org?

I very thank you if you can recommend what OS distribution and what
kernel version
are put together can achieve the maximal stability.

Thank anybody!
