Default beta 4.9.4 dropping connections
Greetings,

we'd like to get as much feedback as possible for a rare bug where Limewire drops all existing connections and refuses to connect unless you restart.

The main details we're interested in are:

* Your OS version
*Your Java version
* Whether you have a firewall or not
* Whether you were on the computer when this happened, or whether you were away and found Limewire disconnected when you came back
* Were you a leaf or an Ultrapeer
* Did you have many active downloads.

Also, it would be very helpful to provide us with a sample bug report if LimeWire goes in that state. To do that you can go to Options->Bug Reports-> View Sample.

Edit: also, if you know how, please get us a stack trace. If you don't know how to do that don't worry.

Thank you again for your help. These beta series have come a long way thanks to all of you.

I had this happen this night. It was in that state in the morning, so I did not see it happen.

It is on Win XPsp2. Java -version:

java version "1.5.0_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)

Im heavily firewalled currently (outside my control), only outgoing TCP connections work via some NAT, no UDP transfers work.
Very few downloads complete in such an environment.

The computer is a leaf and had about 10 downloads pending, but none of them where downloading as I went to bed.

Thanks a lot. If you have the chance, can you see if limewire in such state is capable of performing any i/o ? The easiest way to test that would be to telnet to localhost 6346 and see if the connection gets accepted. Browse host from another machine would do too.

Thanks!

What do these "Timeout guard" threads do? I can't remember seeing any of them on linux...

Timeout guard is part of HttpClient -- it was built for Java 1.3, so it uses an extra thread to do socket connection timeouts.

See http://limewire.org/fisheye/viewrep/...ler.java?r=1.1 , http://limewire.org/fisheye/viewrep/...ava?r=1.6#l652 , & the various socket factories.

So how does one get one of these under Windows if one starts using LimeWire.exe? I know how to generate them on Unix, but on Windows I have never done it.

Just happened to me. No firewall, but it suddenly started incorrectly showing a firewall in the status bar and four red bars. It refuses to reconnect, saying I have no functioning network connection, which is false. And in the stderr console I found something extremely interesting.

Anyone care to explain why Limewire is trying to connect to www.ebay.com? I can't think of a legitimate reason for it to contact that particular host. I do hope you aren't planning on introducing spyware in version 5 or some such. Big commercial sites are the last place I expect it to be connecting.

And an example bug report, just for completeness, after hitting file -> connect for the umpteenth time with no sign of it establishing any connections:

When LimeWire can't make a Gnutella connection and hasn't been able to connect to anyone at all, it tries to do a HEAD request to a few very well-known sites, to detect if an internet connection is active at all. The list is here: http://limewire.org/fisheye/viewrep/...ava?r=1.14#l47 .
