excessive wakeups

I'm trying to debug an AIR application that used to work. Now each time i launch adl in debug mode (-debug=true), 20 seconds after correct start of the application, it is freezing, and i've the following message in Mac OS console :

`kernel[0]: process adl[1413] caught causing excessive wakeups. Observed wakeups rate (per sec): 1275; Maximum permitted wakeups rate (per sec): 150; Observation period: 300 seconds; Task lifetime number of wakeups: 45073`

I've tried many things :

- Creating a new Mac User, expecting a preference problem

- run OS X in safe mode

- Run Flash Builder with Java 1.6 instead of 1.7

- Try to switch back to AIR 3.1 instead of actual AIR 3.7 sdk

Nothing works.

The only thing that removed the problem, is to add -debug=false in Flex compiler parameters, but of course, i cannot debug anymore my application..

Any clue ?

Added extract of the Mac os console dump :
