Tracker fails.

[Repentinus]

Each night before I go to bed I start up uTorrent in what I call "Don't care about connection" mode so that I can seed as many things as possible. Now I've noticed when I wake up all my torrents' trackers will be offline. ALL OF THEM!? What gives. I can stop of transfers, close uTorrent, and reopen and restart everything and it will be fine. I have no idea what causes them to go down in the first place. Also I've tried to update the tracker to no avail.

What error message are you getting on the general tab when this happens?

And what is this "don't care about connection" you speak of? I hope it's not some wild configuration with insane connection numbers and unlimited upload speed.

[Repentinus]

The tracker will show as offline. I don't get any specific error message.

My official "Don't care about connection" is thus:

# of connections: 200

Max # of peers per torrent: 100

# of upload slots: 50

Download speed: Unlimited

Upload Speed: 20/kbs

Nope, that's worse than unlimited upload speed.

Each active torrent is trying to get 50 upload slots. Each upload slot takes a percentage of your upload speed.

So with just 10 torrents, that's potentially 500 upload slots...

20 KB/sec split 500 ways is essentially giving nothing to alot of people at once and trying to use 30+ KB/sec upload bandwidth to do it!

If your connection can only really upload about 25 KB/sec, that overload alone may explain the errors you're having.

With lots of torrents you can set upload slots as low as 1, though 2 or 3 upload slots may work better.

Try to have no more TOTAL upload slots (upload slots x active torrents = max TOTAL upload slots) than you have KB/sec upload speed.

If you only had 5 torrents going, you could allow 4 upload slots per torrent.

Your 20 KB/sec upload speed would be split 20 ways so each upload slot gets about 1 KB/sec...it'd still be pretty slow for someone downloading from you, but that's better than just giving them lots of wasted data.

@Repentinus: Did you happen to change the net.max_halfopen? If so, to what? And what is your TCPIP.SYS patched to? The number of connections is indeed, as I was suspecting, "insane." Very high, for no logical reason.

[Repentinus]

Thanks for the info Switeck.

Ultima, no I didn't change the net.max_halfopen. And call me a newb, but I'm not sure exactly what a TCPIP.SYS is nor what I have it patched to.

[Ultima]

If you're running Windows XP with SP2 installed, try patching the TCPIP.SYS file the patch from with http://www.lvllord.de

Also, you might want to disable DHT and UPnP if that doesn't help (though I doubt this would help).

thanks ultima!

i ran sys restore and it must have reset tcpip connections back to ten and all torrents were red

I have been experiencing the same problem as Repentius for the past few days, whereas previously I had not had any problems with trackers. There seems to be a similar complaint in thread http://forum.utorrent.com/viewtopic.php?id=14686.

I have not changed any setting on my PC or uTorrent. When starting uTorrent everything, including my uploads and downloads, will work normally, however if I leave the program running and check back later, all the trackers report the tracker status as being offline and of my downloads will have stopped. Setting my preferences to connect on a different port does not restore the trackers. However, if I shut down and I restart uTorrent, all the trackers are immediately online again. Since this has happened several times, I really do not think this is the fault of the 20 or so trackers.

I will try and time uTorrent today and see how long it takes for the trackers to go offline - i'm guessing it's anywhere from 30 minutes to a couple of hours. If any more info is required, I am happy to supply to try and get this fixed.
