Comment (by punkrats):

 I tried 3 more configurations and the process always died after 26,5 hours
 as before. My latest command is:

 {{{
 ffmpeg -y -re -i concat.index -c copy -bsf:a aac_adtstoasc -r 24 -copytb 1
 -fflags +igndts+genpts -f flv 'rtmp://server.local/live/stream/test'
 }}}

 I am sure now that FFmpeg has some kind of hard limit, maybe because the
 PTS is so far off. I can't explain why the PTS has such a huge negative
 value, though.
