13 h 31 mn 33 s +- 5s after being launched, jackd is overflown by XRUNS, crunching ad libitum all machine ressources. Reproducible: Always Steps to Reproduce: 1. Jackd launched automaticaly by qjackctl (jackd -R -P89 -dalsa -r44100 -p512 -n2 -D -Chw:2 -Phw:2 -s -Xraw -zs) 2. Wait for 13h31mn35s (using jack clients or not) Actual Results: ======== Traces when problem occurs (no client registred) ===================== 23:34:39.236 XRUN callback (1). delay of 48867.000 usecs exceeds estimated spare time of 11587.000; restart ... ----- preceeding entry repeated 5 times ------- 23:34:40.237 XRUN callback (6). delay of 38983.000 usecs exceeds estimated spare time of 11579.000; restart ... ----- preceeding entry repeated 8 times -------- 23:34:42.237 XRUN callback (14). ..... And so on ad libitum ..... media-sound/jack-audio-connection-kit-0.118.0 USE="-3dnow alsa (-altivec) (-coreaudio) -cpudetection -debug -doc -examples mmx -oss sse" Gentoo-Sources 2.6.34-r12 Could be a coincidence but I think it is worth to mention : 7FFFFFFF / 44100 = 13 h 31 mn 35 s approx ! Would there be somewhere some signed long += sampling frequency every second since jackd launch ?

The problem now occurs systematically 12 h 25 mn 36 s +- 5s after jackd launch. There again : 7FFFFFFF / 48000 = 12 h 25 mn 35 s approx ! - If I change jackd sampling rate to 48Khz but keeping the Multi Track Internal Clock to 44.1, the problem still occurs systematically within the preceeding 13 h 31 mn 33 s +- 5s figure. => We would definitely get some trouble triggered by the overflow of some signed 32 bits word but linked to the M-Audio-Audiophile-24-96 Multi Track Internal Clock value.
Please retry with media-sound/jack-audio-connection-kit-0.121.3
(In reply to comment #4) > Please retry with media-sound/jack-audio-connection-kit-0.121.3 Thank you Pacho for caring. This bug impacting on jackd 0.118.0 under gs 2.6.34 (alsa 1.0.23) Also occurs identically on jackd 0.121.3 under gs 3.4.9 (alsa 1.0.25) Further investigations I achieved on this topic show that : - It only occurs if jackd is launched -Xraw. - IT never occurs if jackd is launched -Xseq. This (in addition with the fact that I carefully parsed jackd's code) would tend to transfer the responsibility of this bug from jackd to Alsa raw midi. But I did not come through Alsa raw midi yet.
