After launching my app in debug mode, app starts correctly, and after few seconds, apps completely freezes, there is no possibility to pause it, and Mac OS console gives such message :
06/08/2014 17:27:58,000 kernel: process adl caught causing excessive wakeups. Observed wakeups rate (per sec): 1278; Maximum permitted wakeups rate (per sec): 150; Observation period: 300 seconds; Task lifetime number of wakeups: 45028
Note that on another mac, i don't have that issue, with the same application.
After a lot of searches, at least i have an indication. When i set -debug=false, i don't have the issue anymore. But of course, i can't debug my file, so it is not of a great help, but maybe this will lead to an idea to you all..
Note that Apple support was indicating me that by creating a new user account on my Mac i could have solved it. I tried, and it seems to work for few hours. But after the problem came back again with my new account.
Of course still looking for a solution , it is very very annoying.
