I\'ve diagnosed a strange behavior in an app : after 10 minutes or so, the CPU usage goes to 100%. There\'s no leak in the app, and it happens while the app is doing nothing.

    When profiling with Instruments (Time Profiler), look to see what method is using the majority of CPU time. Trace the calls back to see why.
