Torrent stopping and starting

[Shabtai1024]

I have never had this problem before and I haven't had any difficulties with any torrents I've downloaded since (concurrently).

I've been downloading a 60+GB torrent for a few weeks now.  A seed rarely pops up but peers who have different sections of the torrent come and go often enough for me to keep trying.  The problem is that it keeps stopping and starting for no apparent reason even when I'm connected to the peers who have the bits I want.  Vuze also shows that these peers are choking me as well as being choked by me even when I have pieces they don't.  I must say I find it all quite frustrating.

Sounds like a classic example of traffic shaping to me.


first check here and locate your ISP.

then read this for suggestions on how to avoid your ISP's efforts (if necessary)

The words here and this are links ;-)

I've downloaded numerous torrents before and since starting this one and never encountered this problem.  Why (or even how) would my ISP throttle this one torrent?

ISP's can start traffic shaping at any time.  Maybe they were not shaping before.  Maybe they only shape at certain times of the day.  Maybe there is a certain country (or countries) which your ISP  is specifically blocking and the seeds for the large torrent are all located in that/those country/countries.  Maybe that large torrent is only using a tracker (not DHT and peer exchange) and the traffic shaping your ISP is using can only block traditional trackers and not DHT and or peer exchange.  All of that has been known to happen before.  Again take a look at the links I provided and see if that does any good.  The steps suggested can often circumvent the problem.

If it does not . . . I can provide you with a link to test if your ISP is indeed traffic shaping.  But the behavior you are describing sounds a lot like traffic shaping.  ISP's do crazy stuff.  Anyone who has been heavily invovled in torrenting has heard lots and lots of stories like the examples I gave.

I will try.  My ISP is not on the list but its parent company which handles their business accounts is. I didn't think it was possible to throttle one torrent while concurrently allowing several others.

It is [possible] kind of.  But only in a very certain set of circumstances.  Namely that one torrent is acting like a private torrent and the others are acting like public torrents.  It is rare . . . but I have seen one case like that . . . I do not know . . . about 5 or 6 years ago.  However, the steps outlined in that second link I posted . . . even if they do not directly help the issue you are having are all good things to try.  They are certainly not going to hurt anything.

If that does not resolve the problem post back . . . I can not think of other things to try right now . . . but there is usually something else to try.  LOL

Good Luck!

What version do you use? Did this happen before 5.4? It sound like my problem here.

The torrent was stopping (and by stopping I don't mean slowing down, I mean actually stopping and starting the torrent within the program) before the update.  It runs for anywhere from 30 sec. to a couple minutes and then stops just as if I had scheduled it to stop and then, after a few seconds, it rechecks, scrapes and begins downloading again.

No dice.  thank you for trying.

It really sounds like you are being traffic shaped to me.  If you did a full install of Vuze is it possible your settings got overwirtten and that your ISP is actively traffic shaping the default torrent port.

So did you change your default torrent port to a port in the range of roughly 50,000 to 60,000 (the acutal range is a little larger . . . but I can never remember it exactly so I just give this range as an approximation)?  If not please try that.  I am about 98% sure that is covered in the links I gave you but I thought it would be reiterating. If you need help with that . . . let us know and someone will tell you exactly how to change that.

I need to find a link to check if you are being traffic shaped . . . because this behavior is exactly what happens when you are traffic shaped.

My point here is that even if the outlined steps in that second link did not help you . . . it does not mean that you are not being traffic shaped.

Give me a few minutes and I will find a good traffic shaping checker for you to use.

That did not take long LOL

try that.

If as I suspect it shows you are being shaped (and changing the port did not help) we can talk about your options.

The attached test results reveal no issues with my ISP.  Should I still try changing ports?
