true, but JACK almost does this by itself. when run with -R, a highpri SCHED_FIFO task runs every 5 (?) seconds, and requires that the engine has checked in since the last time. this prevents loops within JACK from stalling the entire system. anyway, the fact that ctrl-alt-sysrq doesn't work either is a good indication of a deeper problem than a runaway SCHED_FIFO task. i think. --p ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
