I don't know why but timidity sometimes gets stuck in an infinite loop when my system is under heavy disk I/O load. Backtrace from gdb: #0 0x00007f7f29caca57 in ioctl () at ../sysdeps/unix/syscall-template.S:84 #1 0x00007f7f2c31f789 in snd_seq_hw_get_queue_status (seq=<optimized out>, status=<optimized out>) at /usr/src/debug/media-libs/alsa-lib-1.0.29/alsa-lib-1.0.29/src/seq/seq_hw.c:199 #2 0x00000000004a887d in get_current_queue_position (ctxp=0x82dbc0 <alsactx>) at alsaseq_c.c:427 #3 0x00000000004a905a in doit (ctxp=0x82dbc0 <alsactx>) at alsaseq_c.c:498 #4 ctl_pass_playing_list (n=<optimized out>, args=<optimized out>) at alsaseq_c.c:395 #5 0x000000000041b77b in timidity_play_main (files=0x7ffd58ee9690, nfiles=0) at timidity.c:5655 #6 main (argc=<optimized out>, argv=<optimized out>) at timidity.c:5935 Repeatedly doing "finish" gets it stuck at the "doit" frame. If whoever handles this needs me to rebuild timidity with more debug or less optimization let me know.
