nfnl_listen: recvmsg overrun: No buffer space available" in nfct_event_conntrack() call

[Павел Коколемин]

Hello!

I am using libnetfilter_conntrack for log all connections passing via my router
(new & destroy messages).

When LAN users start network scanners (NetLook, for example),
sometimes I receive error in console:
"nfnl_listen: recvmsg overrun: No buffer space available"
generated in nfct_event_conntrack() (recvmsg() returns ENOBUFS error code).
This message generated in nfnl_listen().

When this happens, information about new/destroyed connections is lost?
How I can fix this? If this error in kernel settings?

I am using Gentoo, kernel 2.6.19-r3, try libnfnetlink-0.0.25 and
libnetfilter_conntrack-0.0.50
