Low seeders -> torrent dies, stop/start -> magically revives? Wtf?

Actually, it would seeing it's not related to this particular tracker.

Indeed, it's a question regarding the torrent protocol.
And I think I just found why. I was looking at the peers tab and I noticed the "flags". I looked for them and found them in uTorrent's FAQ. Interesting. It seems whenever the download stops the peers show the "DS" flag. More searching and I found out about the "snubbing" and "choking" here. And a problem similar to mine here.
I think it I understand it more or less, and it makes sense for a healthy swarm. But nothing makes sense when there are SO LITTLE peers. When there are 2 seeders and 1 leecher, why in hell stupid uTorrent snubs them? It's the ONLY source of data. As far as I understand then it's a problem on my client "banning" them until they decide to send the data. But once snubbed it looks like the seeds never send data again and only a start/stop fixes it. I'm kinda lost here. What to do? Why clients are made to keep that behavior with poor swarms of very few ppl, it should be much more forgiving before snubbing someone. And in case there's 1 or 2 seeders never snub at all.
Ideas? I'll read more tomorrow, I'm kinda tired now and all this is a bit... obscure. To sleep >_<

Shouldn't be, nope. The update interval is set by the tracker, not by the client. Any client that overrides that and just updates whenever the heck it wants is a bad client.

That may well be the reason. Clients usually snub seeds that frequently send bad data or fail to send data within a certain amount of time (note that the snubbed flag indicates that your client snubbed the peer, not the other way around). I would expect this to not reset if you stop and start a torrent, but perhaps clients need some way to refresh their knowledge and this is the best way to do it.
The seed may be temp-banning you for eating up so much of his bandwidth. If you were the seeder, you'd probably do the same to someone who asks for 100 pieces at a time or something. It's probably a safety thing. I'd expect that lowering the max number of connections per torrent in your settings should help with that.

i've seen that happen on some buggy download managers, not necessarily torrent manager, but scarce on torrent managers.
download a regular file, pause->continue and see a wooping 300+KB/s on a 2mbps line, it should be impossible really.
ok as for the issue, are you running on default utorrent settings or did you tweak them? same goes for some OS internet tweaks, download managers hates those tweaks.
edit: i think the "maximum connection globally/per torrent" details to how many peers/seeds can connect per torrent at once, not how many pipes/connections per peer or seeds.
megido-rev.M:
^ Yes. 'Connections' in that context is synonymous with 'connected peers'.
