[linux-audio-user] Please, help with this JACK crappy noise!

Hi, Many Musix's users have this problem: in a moment, JACK's apps begins to make some continuous crappy noise. So I see JACK messages and I can debug it a little: [no noise] load = 44.3842 max usecs: 1267.000, spare = 1635.000 load = 44.9522 max usecs: 1321.000, spare = 1581.000 load = 44.3059 max usecs: 1267.000, spare = 1635.000 load = 44.1895 max usecs: 1279.000, spare = 1623.000 load = 44.3552 max usecs: 1292.000, spare = 1610.000 load = 45.0584 max usecs: 1328.000, spare = 1574.000 [noise] load = 61.8986 max usecs: 2285.000, spare = 617.000 load = 68.7853 max usecs: 2196.000, spare = 706.000 load = 80.8778 max usecs: 2698.000, spare = 204.000 load = 80.6353 max usecs: 2333.000, spare = 569.000 load = 79.3080 max usecs: 2263.000, spare = 639.000 load = 79.1096 max usecs: 2290.000, spare = 612.000 load = 79.6650 max usecs: 2328.000, spare = 574.000 load = 78.5989 max usecs: 2250.000, spare = 652.000 load = 76.1017 max usecs: 2136.000, spare = 766.000 load = 64.8082 max usecs: 1553.000, spare = 1349.000 [no noise] load = 51.3738 max usecs: 1101.000, spare = 1801.000 load = 43.9157 max usecs: 1058.000, spare = 1844.000 load = 40.1867 max usecs: 1058.000, spare = 1844.000 So, what's about this "max usecs:" and "spare"? What does it means? It happends with any kind of kernels, realtime patched or not, with any JACK setup, and with a system that has been tuned to achieve hi performance with JACK (rtirq, etc.) When I disable the capture ports into JACK, it almost doesn't happens... Could you help us?
