That probably means some debug message from alsa-lib where for example pcm_dmix.c:1024 is a source file 'pcm_dmix.c' and :1024 is a line where the "falling" function call is. It probably tries to open '/dev/shm/jack-0/default/jack_0' maybe your alsa configuration is a problem, or missing some kernel functionallity (just guessing). Using 'jack-audio-connection-kit'?
