Subject: recording problem (underrun)

Hello again!
  I got another problem. I did some realtime recording with multitracks. I
called:
  ecasound -a:1,2 -i alsa,in1 -a:1 -o out1.wav -a:3 -i null -pn:metronome,120
-a:4 -i monitor.wav -a:2,3,4 -o alsa,default
  When I record I get occasional underruns or whatever. It pops now and then.
Some system-info:
  700Mhz cpu (don't know exactly) 128MB ram, no x-server (even killed stupid
apps like cron, sshed, nscd, etc.), kernel 2.4.19 (NO lowlatency patch)
  I ran ecasound as root with realtime-scheduling.
  Any ideas why this would happen? What can I do about it?
  Kindest regards
        Julien
