 '''Summary of the bug:'''
 I'm streaming from one machine (let's call it FFMPEG_1) to another
 (FFMPEG_2) through RTMP. If there is a network drop both FFMPEGs hang and
 do not quit. When network gets up again they quit with error. This is ok.
 But when connection is lost / dropped and you kill FFMPEG_1, network gets
 up, FFMPEG_2 will stay hanged forever and will reject any incomming
 connection.

 FFMPEG version does not matter. I've tried 4.1.3 on both machines. Didn't
 help.


 '''How to reproduce:'''
 FFMPEG_1 - Running on Ubuntu 18.04.1 LTS
 {{{
 % ffmpeg -y -re -i video.mp4 -c copy -c:a aac -ac 2 -ar 44100 -f flv
 rtmp://192.168.100.6/live
 }}}

 FFMPEG_2 - Running on Windows 10 Build 1809
 {{{

 * '''Steps to reproduce'''
   1. Simulate network connection drop on one machine - does not matter
 which one (disable network adapter or unplug ethernet cable)
   2. Kill FFMPEG_1
   3. Enable network adapter / plug-in ethernet cable
   4. FFMPEG_2 is now freezed forever and does not accept RTMP input
 anymore

 I'm sorry for my poor English O:)
