VoiceOver will report that an application is busy if it does not quickly respond to accessibility requests. All accessibility requests come in on the main thread, so you have 2 possibilities:
1) You main thread is busy doing something else
2) You are taking way too long to respond to accessibility requests
The problem could be one or both of them, you will need to use sample, or the Instruments Time Profiler to figure out the problem.
