Transmission DHT dht_periodic failed

[dk_giuse]

I have compilated OpenWrt? trunk (r23867) including packages transmission-deamon & transmission-web.

it use use 100% of Cpu, and in system log, i read to many error..

I'm a little puzzled by that. Unless I'm mistaken, there's no way dht_periodic can return -1 with errno unset.

There are only three return points in dht_periodic(). One of them is hardcoded to "return 1;" so we can discard that one from the list of suspects. The other two are from checking the return value of a call to recvfrom():

            rc = recvfrom(dht_socket, buf, 1536, 0, source, &sourcelen);
            if(rc < 0 && errno != EAGAIN) {
                    return rc;
            }

and

            rc = recvfrom(dht_socket6, buf, 1536, 0,
                          source, &sourcelen);
            if(rc < 0 && errno != EAGAIN) {
                    return rc;
            }

And the manpage for recvfrom() says errno will be set if recvfrom() fails.

dk_giuse, do you have any idea what version / type of libc your system is running? For example, is it GNU libc, or uClibc, and what version number?
