This warning is usually a symptom of high CPU usage, for example, creating and destroying many event instances every frame. You can try connecting the [FMOD Profiler](https://fmod.com/resources/documentation-studio?version=2.02&page=profiling.html) to determine which events are hogging resources.  
What version of FMOD and Unity are you using and how often is this crash occurring?
