I explore that behavior and…
In standart httpd thread:
THREAD(Service, arg)
{
    TCPSOCKET *sock;
    FILE *stream;
	NutThreadSetPriority(254);

    for (;;) {

        if ((sock = NutTcpCreateSocket()) == 0) {
            NutSleep(5000);
            continue;
        }
        NutTcpAccept(sock, 80);
        while (NutHeapAvailable() < 8192) {
NutHeapAvailable());
            NutSleep(1000);
        }
		if ((stream = _fdopen((int) ((uptr_t) sock), "r+b")) == 0) {
			syslog(LOG_INFO, "Error opening stream… 8(");
        } else {
            NutHttpProcessRequest(stream);
            fclose(stream);
        }
        NutTcpCloseSocket(sock);
    }
}
And when I open all 3 connection, I get syslog message!!!
So, OS can’t open sock???
If I break one of connection, then http work fine, until I not connect
broken TCP connection….
