Jack,

Can't get it to abort when the Jack period is 256. Tried it several 
times without aborting. My .jackdrc then was: /usr/bin/jackd -R -dalsa 
-dhw:0 -r44100 -p256 -n2

As soon as I changed my jack settings to 64 frames: /usr/bin/jackd -R 
-dalsa -dhw:0 -r44100 -p64 -n4, Jamin aborted at the end of the first 
export I tried.

I've attached the gdb.log with the content you asked. Kernel: Linux 
2.6.31-9-rt #152-Ubuntu SMP PREEMPT RT Thu Oct 15 05:01:14 UTC 2009 i686 
GNU/Linux. All packages from the Ubuntu Karmic standard repos.

Changing the jack settings to 128 frames: /usr/bin/jackd -R -dalsa 
-dhw:0 -r44100 -p128 -n2, did not show the abort either, tried it 
several times in a row.

As soon as I changed it back to 64 as above, trouble started again.

I'm very curious about the magical 256/128 ...

If you need more info, or want me to try other things, let me know.

Regards,
Kees
