utorrent exceeds max number of connections set

[odysseusky]

my internet is 1.5Mbit/256Kbit

in preferences -> bandwidth -> number of connections

global max number of connections is set to 100

max number of connected peers per torrent is set to 70

number of upload slots per torrent is set to 3

however, sometimes after utorrent has been running for a while, the total number of connections of utorrent goes over 100, not just by a little bit, but something like 200+

any idea what's going on? is there any other setting that overrides the global max number of connections?

thanx a lot in advance....

How are you measuring the connections?

[odysseusky]

i use outpost firewall to check how many connections utorrent is using.

and every time the connections go over 200 (as shown in outpost firewall), the decrease in speed is very obvious, i can't even open webpages

[DreadWingKnight]

Then there is the very real possibility that it is:

1> counting connections that aren't open.

2> counting UDP traffic as connections (which is obnoxiously stupid as UDP traffic is connectionless)

[odysseusky]

outpost shows no UDP traffic

if it is indeed case 1, then how is the bandwitdh jammed? the connections are closed, aren't they?

r u saying that if i switch to another firewall or none at all, this wouldnt happen at all?

uTorrent v1.8 has a serious problem with its half open connection limit handling.

The latest v1.8.1 beta should have that cleared up, so try it.

What is net.max_halfopen set to in your uTorrent anyway? (it should be 8)

Other things in uTorrent that temporarily make connections or use UDP packets:

DHT, LPD, UPnP, NAT-PMP, and Resolve IPs (right-click in PEERS window of an active torrent to disable).

Disabling them temporarily can at least let you see if they're the cause.

You might also want to try the 256 kilobits/second upload settings found in my Speed Guide -- 2nd link of my signature. My guide is far more conservative in max connections than uTorrent's normal Speed Guide (CTRL+G).

Outpost has always had huge problems with connection counting, though. It's very, very very wrong.

[odysseusky]

Can outpost counting the connections wrong actually jam the bandwidth?

net.max_halfopen is set to 8

and DHT, LPD, NAT-PMP, UPnP has always been off, i'm turning off Resolve_IPs now to see if it helps

[Firon]

I believe that Outpost actually HOLDS connections open for a lot longer than they should be.

Regardless, you should give updating to 1.8.1 a try.

[odysseusky]

I tried everything Switeck suggested on 1.8, and it's not working.

Now I'm testing 1.8.1, if it doesn't work either, then

1) can I conclude that it's because Outpost keeps the connections open longer than they should?

2) if (1) is true, why does it affect only utorrent, but not firefox or ie?

[Firon]

Firefox opens very few connections compared to utorrent. That's why it would be unaffected.

[odysseusky]

i had 1.8.1 running for couples days now, everything's fine

Thanks
