[LAD] jack disconnecting my app

Hello all, i have written an jackified application for a customer. the main application play a couple of audiofiles (wav) with some effects and filters. Everything works fine so far. From time to time, while loading some more files, jack disconnects my application. the loading process is a seperated thread. i use the thread implementation from wxWidgets, which uses pthreads. Neither my app nor jack crashed, they are running but my app tell my "zombified - calling shutdown handler" the output of jack is. --------------- schnipp bash-3.00# /usr/local/bin/jackd --realtime -d alsa jackd 0.100.0 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods nperiods = 2 for capture nperiods = 2 for playback **** alsa_pcm: xrun of at least 0.662 msecs **** alsa_pcm: xrun of at least 4.624 msecs **** alsa_pcm: xrun of at least 4.950 msecs **** alsa_pcm: xrun of at least 68.566 msecs **** alsa_pcm: xrun of at least 48.265 msecs **** alsa_pcm: xrun of at least 4.413 msecs **** alsa_pcm: xrun of at least 6.883 msecs **** alsa_pcm: xrun of at least 126.050 msecs **** alsa_pcm: xrun of at least 62.059 msecs **** alsa_pcm: xrun of at least 51.514 msecs **** alsa_pcm: xrun of at least 12.643 msecs subgraph starting at soundroom timed out (subgraph_wait_fd=9, status = 0, state = Running) ----------- schnipp the xruns only appear while load sounds. kernelversion is Linux soundroom 2.6.15.6 #7 SMP PREEMPT Fri Jun 16 22:18:26 GMT 2006 i686 unknown unknown GNU/Linux more /proc/asound/cards 0 [Gina3G ]: Echo_Echo3G - Gina3G Gina3G rev.0 (DSP56361) at 0xea000000 irq 50 1 [CK804 ]: NFORCE - NVidia CK804 NVidia CK804 with ALC850 at 0xea105000, irq 217 and i use the gina3G and now the questions; - is there any way, to get more infos out off jack - any way to keep the app connected or a hint to avoid the disconnection - some days ago i testet the jack version 0.103, but jack uses 100% cpu without any app. just starting qjackctl showed that. thanks very much for some hints. c~
