Many attempts before stable connexion since 0.13.1 (or 2)

Hi,

I’ve noticed for few days ago :

syncthing needs to try many times before getting a “stable” connection.

Is this normal or may I configure something to ease its job ?

What do « use of closed network connection » « closed: write tcp » and « closed: unexpected EOF » mean ?

There is a bug open on the tracker about this (dial race). If you could get the logs required there and post them, that would be useful.

[quote=“AudriusButkevicius”] Can you run with STTRACE=discovery,connections env var and provide logs from both sides? [/quote]This, I guess.

Sorry for my ignorance but how do I do that - (L)Ubuntu 14.04 on the 3 machines ?

I am sure google can answer how to set an environment variable on your OS.

This should help me https://docs.syncthing.net/dev/debugging.html

Is this useful : http://pastebin.com/DXSE5i3r ?
