Here a link to the tool that I use to stress netlink sockets.

Thanks for the link.  I'm afraid that your kernel module is simply
buggy.

First of all as I explained before the kernel must never wait.  It has
exactly the same effect as extending the receive queue length.

Secondly each of your user-space messages is producing a number of
replies.  This should be done as a dump operation.  If you do it as
a dump operation, then you will never get overruns because the kernel
never sends more than the user can handle.
 

I'll adapt the module to use dump, I still think that I can reproduce 
the problem.

thanks for the review, please stay tuned.

regards,
Pablo
