Net goes down when starting one P2P but..

[bbwannabe]

not when using another.

I have two p2ps programs on my computer (utorrent and emule). Over the past few days I've had connection issues, sometimes all day, sometimes it works fine but has occassional drops in connection. Today after resetting my router/modem I could connect ok, had torrent running for a few ours as well as irc, but as soon as I start emule, it drops (I use it sometimes when net drops as it shows me a graph of when it is working fine and when it doesn't). I close it down and it works fine again. A few hours later I give it another try and the same thing happens.

I think it's too coincidental of a situation, so was wondering if there was a reasonable explaination?. Seems weird to me.

It sounds like your overloading your connection/router.
You should only use one peer2peer program at once as too many connections can cause your connection to suddenly drop out

But i've had the exact same no of connections for a while in both programs and with no problems until just a few days ago.

try updating the firmware fo the router, sounds like hardware issue with it rather than a VM issue

[bbwannabe]

lol, updated firmware router 2 days after i had connection problems, and am still having them *Oddly, both programs are working now and seem fine but i'm holding my breath until at least 24hrs goes by without any issues.

Lol they are on to you!

tried pluggin your machine directly into the modem to see if it resolves the problems?

resolves 100% of problems whenever i have internet issues.

as far as i know vm dont monitor and regulate connections on p2p or any other protocol. however they still monitor bandwidth regardless, using stm, which shouldnt affect connection issues.

If you're using XP SP2, have you increased the number of half-open TCP connections it can use?

TorrentFreak wrote an accessible explanation of the problem over 2 years ago -- the article focuses on bittorrent but the same is applicable for all P2P apps.

More technical info and the downloadable patching routine is available from LviLord.de.

I use XP-Antispy and changed the default no of connections to unlimited, so it can't be that unfortunately. Will give the direct connection (minus router) approach a try next time the net cuts off.

XP-AntiSpy seems to recommend that you set the number of permitted half-open connections to 10 -- most P2P-familiar sites recommend 50-100.
AFAIK there is no unlimited setting.

Recommend you read (any of) the articles I took the time to link to, download the patch and check your settings.

[bbwannabe]

ok unlimited maybe exaggerating it, it's "Current maximum concurrent half-open connections: 16777214", it recommends that I don't change any settings in versions > than 1.7 utorrent (can't find it in settings anywhere tbh). I'll change the half connections from what it is now to 100. But part of me still thinks it isn't the cause of the troubles of the past few days.

Doesn't hurt to give it a go.

[ceedee]

I doubt this will, on it's own, turn out to be the *cause* of your recent problem -- just another in the list of things to rule out.
:-)

I'm wondering if there's a way to monitor which emule servers you connect to before the speed crashes?
I notice that some folks on the emule forums are reporting "abnormal" cpu loads -- seen anything weird there?

Good luck!

(In uTorrent v1.60, you could change the value of "net.max_halfopen" under the Advanced Options in Preferences. I've still not got around to playing with 1.7!)

Still think they are on to you!!! haha

Have you tried uninstalling - reinstalling or installing and trying a different p2p - like bitcomet or something?

Funny you should mention that...

I had the same situation the other day when I tried to do a mass server ping within a game, got through a couple then totally stopped my connection.

Easy enough to fix in my case as I use a software router until my Business roadband gets installed and I just turned off max connections per user. (only two of us and only I tend to break it )
