And what is the problem? (or did I overlook something?)

Hello.
Help me please!

I use netfilter for the project traffpro (billing system), has faced such
problem, at obtaining MAC of a source address I obtain the normal data, but at
loading increase I start to receive instead of MAC addresses:
(The first parameter MAC the address real, second parameter that function
nfq_get_packet_hw () returns me, the third parameter length of the received
address)

90 e6 ba 10 21 ff = 40 0 7f 6 90 39 len: 6

The problem was showed only on 2х computers, attempts to replace the
distribution kit linux haven't resulted in the positive result (were used for
tests Fedora 14 - 16, Ubuntu server 10.04).

Such problem servers only 2, on remaining servers operation excellent at any
loadings.

The only thing that it identical at these two problem servers:
