--- Comment #11 from Pablo Neira Ayuso <pablo at netfilter.org> ---
OK, I found the root cause.

On your side, you are triggering EEXIST on a very big netlink message contain
lots of elements from userspace.

The receive buffer is only MNL_SOCKET_BUFFER_SIZE which is not big enough to
store the NLMSG_ERROR message, which contains the original netlink message as a
payload.

Preparing a patch to fix this...
