[FFmpeg-user] amix fills 16Gb memory, ffmpeg killed

I am trying to join 11 video files, each 3 minutes in length. I can get 
the video rendered correctly, where the audio only lasts 3 minutes from 
input 0. But when I add the amix filter, it fills 16Gb of memory in 2 
minutes and gets it's process killed.

The full command line and output, before and after adding
are in this 43Kb text file:

Is there a better way to write the command?
(without resorting to trimming each file, and then using concat filter.)
Thank you,
