 Reporter:  alexnv         |        Type:  defect                
   Status:  new            |    Priority:  critical              
Milestone:                 |   Component:  Tor Client            
  Version:  Tor: 0.2.1.26  |    Keywords:  download process break
   Parent:                 |  
---------------------------+------------------------------------------------
 What happens:

 1. Start download (from file hosting)
 2. Speed ok, download progress bar is filling
 3. Some time passed...(no alerts)
 4. Speed = 0, a fraction of file is on disk.

 Notice:

 1. I tried to download using Tor 0.2.1.26 and 0.2.1.27
  different files from  different hosts
 with almost the same result: 60-65 mb downloaded on disk

 2. When downloading without Tor (Tor not started),
 using Google chrome browser, all is ok.

 System parameters:
 1) OS Windows XP 5.1.2600
 2) Antivirus Avira (webGuard off, firewall off)
 3) Windows firewall is off
 4) Event ID 4226 Patcher  applied
 5) Mozilla adjusted:
 network.http.keep-alive.timeout:600 (300ms default is OK usually, but 600
 is better.)
 network.http.max-persistent-connections-per-proxy:16 (Default is 4)
 network.http.pipelining:true (Default- false. Some old HTTP/1.0 servers
 can't handle it.)
 network.http.pipelining.maxrequests:8 (No default)
 network.http.proxy.keep-alive:true (Default- true, but double check)
 network.http.proxy.pipelining:true (Default- false) - See NOTE1 below.

 QUESTION:
 What can be done to fix the problem?
