Resource Limit [EXC_RESOURCE]
The process exceeded a resource consumption limit. This is a notification from the OS that the process is using too many resources. The exact resource is listed in the Exception Subtype field. If the Exception Note field contains NON-FATAL CONDITION, then the process was not killed even though a crash report was generated.
The exception subtype MEMORY indicates that the process has crossed a memory limit imposed by the system. This may be a precursor to termination for excess memory usage.
The exception subtype WAKEUPS indicates that threads in the process are being woken up too many times per second, which forces the CPU to wake up very often and consumes battery life.
Typically, this is caused by thread-to-thread communication (generally using peformSelector:onThread: or dispatch_async) that is unwittingly happening far more often than it should be. Because the sort of communication that triggers this exception is happening so frequently, there will usually be multiple background threads with very similar Backtraces - indicating where the communication is originating.
