hmm, that sounds like jackd is kicking ecasound out of the graph for some
reason. It would be interesting to see the jackd logs around the time
ecasound exits.

Alternatively, you could try recording directly without jackd:

ecasound -a:1,2,3,4 -f:32,12,44100 -i alsa,hw:0 \
          -a:1 -f:32,1,44100 -o audio1.mp3
          -a:2 -f:32,1,44100 -o audio2.mp3 -erc:2,1
          -a:3 -f:32,1,44100 -o audio3.mp3 -erc:3,1
          -a:3 -f:32,1,44100 -o audio4.mp3 -erc:4,1

If you get an error from ALSA, the '-f:32,12,44100' doesn't match your
soundcard's hw-capabilityies. You can either try to guess the correct
options, or use "-i alsa,default" or "-i alsa,default" instead of the
above (less efficient, but are more likely to work with different
soundcards).

Of course, the above should work with jackd as well, but if you are not
doing latency sensitive processing, recording directly from ALSA to lame
might be more reliable.
